We have several servers and clients behind a PIX 501 firewall / router. Each server is assigned an outside IP address using NAT, and each server has two internal addresses. One internal IP does not have a NAT address (incoming and outgoing translation), the other does. So:
Server 1 has:
Internal IP: 192.168.1.116
Internal IP: 192.168.1.117
The .116 address is assigned a NAT, let's call it 22.214.171.124. The .117 address is not assigned a NAT, it simply uses the PAT address to go out to the internet just like any other client on the network. Here's the odd part. Internal clients (also with 192.168.1.xxx addresses) can access the .117 address without a problem. The .116 address that has the NAT, however, does not seem to be accessible.
When I attempt to ping the .116 address from an internal cient, I get one reply. The rest of the ping requests time out. Any idea why I would be unable to access an internal IP that has a NAT assigned to it?
Thanks for your time.
