Having a problem, here is the situation.
We have a 2800 router that was set up to perform nat between an internal FA interface (192.x.x.x) and and external GIG interface to the internet. All works fine and has been for some time.
We recently configured another gig port on the router to handle routed traffic coming from another internal site with a different subnet (10.100.x.x). This also works fine. We can access the internet from this remote site and access devices on the 192 network.
IMPORTANT: The 10 network access the internet by going to through the 192 interface to a proxy on the 192 network. they do not use the internet connection on this router
Here is the issue:
From the 10 network when a workstation tries to access a destination on the internet using port 12500 it never connects. I did a packeet trace and can see the packets going to the 192 network but they never return.
Is the traffic NATted when traversing from the 10 to the 192 network? How is that affecting a device on the 10 network trying to access a device on the internet going thru the 192 network with port 12500?
