DHCP is set to disabled and a static IP is set within the range of the IP's handed out by the second router. Setting dhcp mode to relay is not possible without disabling NAT. However, all NAT options under NAT -> ALG are currently disabled yet the Zyxel insists it's enabled.

reset the router to defaults, do the basic security setting changing router's password, configure the wifi parameters (SSID, encryption, channel and all the wifi stuff). Then do again the WAN disabling and DHCP server disabling. Put a free fixed ip of your range (out of your other router's DHCP range) and that's all!

Does anyone know how to get this router into bridge mode? There are no manuals (at least that I can find) on the Zyxel website and the GUI is next to useless. Not impressed with this router at all so far, we are bridging to a DrayTek 2962.

This document explains how to set the standard internet access device VMG series from routing into bridge mode. The bridge mode is used if you require the device to connect via xDSL to your provide...

Thanks, Yes I have seen that article and it bears no relationship to this model sadly. There seem to be no configuration options for the WAN link. I have a feeling that this ISP supplied router is somehow locked down to prevent any changes to the WAN link, they have even told us we are not allowed to change the router, though I am going to argue the point. Perhaps this is a custom firmware or custom managed device.

I want my NAS to be connected to the Internet and therefore only one routing with NAT is enough and thus I bridged mode the gateway. I know how to bridge mode the gateway, but every time I do it, I lose internet connection.

I would just like you to note that exposing a NAS to the Internet may be a bigsecurity hole. NAS devices are not well protected, and when infected can easilyinfect every other device on the local network.

Now I really have a nice bridged network between both routers, that is the 1st router (embedded in the gateway) and the 2nd router, being my 2nd router the main only true router (routing data with firewall, NAT, etc.) and not being merely a repeater or an access point.

I have a Zyxel P660HW-t1 v2 router (which has a DSL port) and a WRT54GL router (which does not) and the exact same situation as in this thread (UPDATE: the connection between both devices is the important part, since I have been able to set the zyxel router to act as bridge by itself quite nicely. I have accessed my internet connection directly through a PC using PPPoE without any problems, the issues arise when I try to connect the WRT54GL router between the zyxel "modem" and my PCs).

The thing is that when I connect the Zyxel modem/router on the WRT54GL's internet port the light doesn't turn on. I can confirm that this port has been working ok, so I'm not really sure what's going between the devices. I checked several settings such as IPs, tried disabling DHCP on Zyxel/Linksys, Firewall on both and still nothing. Also, I tried connecting Zyxel directly to a computer in bridge mode and dialed successfully.

I have even posted a question here before, thinking that what I asked there was the only thing I needed to get things done. Unfortunately it wasn't, and the guy that solved his issue didn't give enough details in his post (and is quite unlikely to give more details since he was an anonymous user).

EDIT: I noticed, in the end, that the router takes a while to tell you it "connected" to the WAN. So a bit of patience may be needed before making hasty assumptions. My case was possibly because of this, in the end.

You should be able to configure your P660 in bridge mode. Once configured in bridge mode configure you WRT54GL to obtain the WAN IP address and DNS automatically. Also, make sure that the WRT54GL's LAN IP address is not the same as the IP assigned to the P660 (192.168.1.1 if following the guide, so something like 192.168.2.1 should work). Make sure the DHCP server is turned on on the WRT54GL and you should be good to go.

Answering yourquestion: other devices like laptop with wireless connection willlost its connection. WLAN is up but internet connection is down. IUse cable connection only for main host. Thought that all routersgive only one connection when bridged.

Looks like myOpenSuse 15 Leap works little different than my Ubuntu server.OpenSuse keeps connection when switching from factory settings tobridge mode. This time I changed only bridge mode NOT firewall, NATor DHCP.

So my Ubuntu serverlost its connection if I wont disable firewall, NAT or DHCP also.Server have quite tight settings and have firewall, DHCP, DNS etcservices configured so that may make the difference. Hope that waswhat you answered.

Sooo, nice progresstoday. My Zyxel 3301 works nice now with my setup. My Suse is a basicclient and works great too. My Ubuntu server needs though some morelove. Needs to go thru the settings and test them.

I'd also like the use a LTE3301 in bridge mode.
But my plan is to recycle the LTE3301 wireless by creating a new VLAN (LAN2+WLANxyz)
I'd connect my router's WAN to LAN1 and one of the router LAN ports to LAN2.
Is the LTE3301 wireless still on in bridge mode?
Can you still access 192.168.1.1?

Hi all, I am planning to get a Belkin RT3200 as recommended by fellow forum members, and install OpenWRT on it. I want to configure VLAN and everything for my home network on the RT3200 without touching the ISP modem. As far as I understand, the way to go is to place the router right behind my ISP-provided modem, and switch the modem to bridge mode.

The LAN client in the Demilitarized Zone (DMZ) is no longer behind this device and therefore can run any Internet applications such as, video conferencing and Internet gaming without restrictions, but with the same reason, it also uncovers itself to Internet security threats.

Our wiki actually has a page for that situation. Basically you would be using the DMZ as an "IP passthrough." How well this works largely depends on how the DMZ is implemented on the ISP router/modem, it may or may not end up as a double NAT with significant limitations.

Poor Man's Bridge Mode This article may contain network configuration that is version dependent post 2021-06 * ifname@interface has been moved to device and device sections * while legacy ifname syntax may work on 21.02 or recent master it is...

I have fiber-optic internet, and the ISP-provided Zyxel basically plugs the internet Ethernet cable into its WAN port. Can I just basically plugs this same cable into my own router instead? Or bridge / DMZ is a must?

Oh that's an interesting question. I'm not sure what features are available on the latest Zyxel software, but I don't think it has bridge mode on it. In any case, bridge mode is normally only needed for wireless networks. If you're connecting to the Zyxel through ethernet, it should be able to do what you want, and bypass it's wireless features.

I'm not familiar with the system you are using, but if you've set it to bridge mode, it might be performing it's own NAT. It might be worth connecting it in standard routing mode to see if this produces the results you desire.

IP Passthrough is supposed to be the same as Bridge Mode AFAIK (correct me if I'm wrong), and when enabled the NR5103E should essentially just act as a modem and nothing else, all DHCP, Routing, QOS etc should then be handled by the passthrough device connected to the NR5103E via ethernet e.g. Aftermarket Router/Mesh system

I did quickly try IP Passthrough on the NR5103E recently with a TP-Link Deco P9 set and had the same problem as @aflatbroke where the Deco was not being passed the WAN IP it was still being given an internal address so it may possibly be a bug, however I didn't thoroughly test and I cant do any further tests as I just sent the Deco P9 kit back as the performance was awful lol

As IP Passthrough didn't work for me when I was running the Deco's I just set the Deco's to run in AP mode instead of Router mode, so that the NR5103E managed all DHCP, NAT, Routing etc and the Deco's became simple access points (this method also avoids double NAT but when you spend good money on a router you ideally want it to be managing everything, hence IP Passthrough/Bridge Mode).

Thanks for your input cryt0ninjaI think to have the WAN IP pass through the NR5103E it doesn't feel like a software bug, but IP Passthrough should do just that! I wonder if it's something to do with it being a mobile sim. My current set up is a hard wired copper to fibre cabinet down the road through a Draytek 130 modem in bridge mode, through Cat6 to a Unifi USG with access points through Unifi AC Pro's. I also have Unifi Nano Beams sending my internet to Neighbour 100m down the road. I get around 50mbps up and 18 down. The system works floorless. But with 5G through the NR5103E giving me between 80-700mbps but latency is terrible. The idea is with IP Passthrough it would be a great solution to have that speed. I too will continue to experiment and post if I find a solution.

Hi Floored, sorry I have not found a solution. It seems this is a common issue with mobile broadband. I now use the 5G NR5103E as a standby as I said latency is terrible and speeds are to erratic. So it sits there costing me 20/month. If you have better luck please post here. Thank you.

After a day or two I hit a problem - my router couldn't get the WAN ip address from the NR5103E... so maybe the required functionality is not quite there yet.

Having tried everything I could find in the web interface, I reset the router to factory and I'm double-NATing again

I have set up my Orbi and it is working fine, however my Zyxel Router from my internet company is still broadcasting a Wi-Fi signal. I assume I need to change the outer to work in Bridge mode. There are 3 setting (ADSL, VDSL and ETHWAN). Does anyone know which should be set to brisdge mode?

It appears this router can be used with different internet connections. Perhaps if you supply the exact model number, we can look at the User Manual and help you log into the router and find the correct setting. (Or, you could call the Internet Service Provider and ask them how to set it into bridge mode. They get this kind of call frequently and may even offer to log in and do it for you.)
