LAN to LAN VPN

[Mark]

This has been a question I've pondered for a long time.

I have a remote LAN of machines that I want to have
access to my corporate LAN. I can take one of them and
establish a VPN connection but do not appear able to
route through it.

Is there something I'm missing or a better way of doing
this?

You can set up a router-to-router VPN. I'm in the process of doing this
right now.

I'm trying to so the same, is there any dis-advantages
though on this like we noticed we had slow downs on the
connection, I heard unless you have a dedicated line for
vpn it'll slow down your network (we're on a public T1),
is that true, thanks

I think it all depends on how much data you're sending back and forth and
how often (constantly or intermittently).

When you say "public T1" do you mean you're sharing it with other companies,
or your organization?

I just got our router-to-router vpn going and haven't noticed a
slowdown......yet.

I meant public internet, with no dedicated line, and the
remote office is in Boston.

Hi there,

The slowdown you talk of is mostly due to the encryption/encapsulation
process taking place between the two routers.

In my experience, cheaper routers acting as VPN endpoints do not have a
hardware VPN processor, instead relying on a software element within the
router. With all the normal router functions to cope with this will
obviously have some sort of slow down effect.

Test it, set up a router - router VPN and ping or copy some data over the
wan. Then do it without the VPN element, ie. open certain ports and try it
again. I bet it will be faster.

What you need to do is to balance acceptable speed loss with required
transit security & cost.

We have used numerous routers for routre based VPN and I prefer the Zxyel
Zywall100 VPN firewall. This is much cheaper than anything comparable (IMHO)
and works fine. We have it over DSL between London/ New York & France. It is
very useable and easy to set up.

hope this helps
