The ip addressing is just theoretical.....not what I actually use.
Hi all. I have an 1811 router. On the FastEthernet interface
I have a primary and secondary ip address.
ip nat inside source static tcp 192.168.250.102 25 68.12.16.30 25 extendable
ip nat inside source static tcp 192.168.250.103 25 68.12.16.31 25 extendable
!
interface FastEthernet0
ip address 68.12.16.30 255.255.255.0 secondary
ip address 68.12.16.31 255.255.255.0
ip nat outside
ip virtual-reassembly
no ip route-cache cef
no ip route-cache
no ip mroute-cache
speed auto
full-duplex
When I add the 2nd nat statement the port 25 does not appear in a port scan on the public ip of 68.12.16.31. I start trying to telnet to 68.12.16.31 using port 25 and the router WAN stops reponding to ping.
Anyone have a similar issue dealing with secondary ip addresses shared by one interface?
