Hi,
I'm trying to add some static mappings to a simple NAT/PAT setup.
Currently, everything is working like so:
ip nat inside source list 50 interface Serial1 overload
!
interface Ethernet0
ip address 10.0.0.1 255.255.255.0
ip nat inside
no ip route-cache
no ip mroute-cache
!
!
interface Serial1
ip address 216.223.xxx.xx8 255.255.255.252
ip nat outside
encapsulation ppp
service-module t1 clock source internal
service-module t1 timeslots 1-2
!
access-list 50 permit 10.0.0.0 0.0.0.255
All is well there... Looking at another customer I set up, the only thing
I added to get their mail server working was a line like so:
ip nat inside source static tcp 192.168.0.45 25 216.223.xxx.xx4 25 extendable
And that works fine. However adding a similar line to the above config:
ip nat inside source static tcp 10.0.0.102 110 216.223.xxx.xx8 110 extendable
ip nat inside source static tcp 10.0.0.102 25 216.223.xxx.xx8 25 extendable
...does not work. Before adding these lines, trying to reach those ports
gave an immediate "connection refused". After adding them (and even
clearing the translation tables and then reloading for good measure), I
simply get a "connection timed out".
Am I doing this right, or is it a bug? IOS is IOS (tm) 1600 Software
(C1600-SY-M), Version 11.3(7)T
I'd hate to have to load a new image on here, as I seem to recall that the
1600 is a bit rough to work with remotely.
Any ideas?
Thanks,
Charles
