I have a configuration similar to the following:
server actual ip:188.8.131.52 (inside local)
server NAT'ed ip: 184.108.40.206 (inside global)
workstation 1: 220.127.116.11
workstation 2: 18.104.22.168
Things work for workstation 1 but not for workstation 2. E.g. when workstation 2 telnet to 22.214.171.124, the telnet session timeout. 126.96.36.199 can telnet to 188.8.131.52.
The arp table of Router2 contains the arp entry of 184.108.40.206, the MAC is the NAT-outside interface of Router1. Router1 and Router2 run OSPF and routing seems not a problem.
I don't understand why things doesn't work for workstation in the segment directly connected to the NAT-outside interface. Any information would be welcome.
Config of Router1:
ip address 220.127.116.11 255.255.255.0
ip nat inside
ip address 18.104.22.168 255.255.255.0
ip nat outside
ip nat inside source static 22.214.171.124 126.96.36.199
