Can BorderManager 3.8 do port redirection for inbound traffic?

I've got a single IP address on the public NIC and need to point
certain traffic to different hosts behind bordermanager. i.e.
terminal server - port 3389, groupwise poa - 1677, etc.

border manager private IP 192.168.0.2
terminal server 192.168.0.3
groupwise post office 192.168.0.1

I understand how easy this is with multiple public IP addresses and
static NAT, unfortunately, I can only get one IP address from the ISP
at this time.

Look forward to reading your responses.


TIA!

Gary

Yes, using generic proxy.

No problem.

It's easy. Set up a generic TCP proxy, for each port/address pair, add
appropriate filter exceptions (to allow the traffic TO the proxy), and
add appropriate access rules (to allow the traffic THROUGH the proxy).

I have several examples in my BMgr 3.x book (see URL below) for various
applications.
