NAT problems forwarding from a routed subnet.

NAT problems forwarding from a routed subnet.

[Henning Wangerin]

Hi!

I'm in control of a larger WLAN network, where we are connected via
a /30 network, and have a routed /28 network that we are going to
forward ip by by to some of our users.

Each location have an 10.128.x.1/24 network where eg 10.128.x.250 is
natted to 10.10.x.250 on my LAN.

That works fine. I can ssh from the WLAN-network to 10.128.x.250 and get
access to the desired server.

I need to get access the same way from the internet, so eg a.b.c.50 is
forwarded to 10.128.x.250.

I'tried multiple solutions, but nothing works.

Any tips/links on how to get it to work?

BTW the network is described here:

You will do same as in 10.128.x.250->10.10.x.250, but on the next router
(with nat capabilityes) to internet. By the way, that link is not working.

Yeah.
The moment you call for help, the solution pops into ones face.

The natting on the client-box is done via scripts, and I counldn't
figure out witch parts to pick out.

It's up and running find.

Hmm. Should be.

Must have been a temporary outage of the old line :-(
That's one more reason the get the new setup running quickly!
