[c-nsp] ip nat inside problem

[jan gregor]

Hello all,

on on of our customer sites we have 1812 router.
Public IP: 1.2.3.4 /30
Lan IP: 192.168.1.1 /24

Router is doing nat in following configuration:
access-list 1 permit 192.168.1.0 0.0.0.255
ip nat pool customer 1.2.3.4 1.2.3.4 netmask 255.255.255.252
ip nat inside source list 1 pool autovia overload
ip nat inside source static tcp 192.168.1.10 25 1.2.3.4 25 extendable

Problem is, that it is impossible to connect to 1.2.3.4:25 from lan:
telnet 1.2.3.4 25
Trying 1.2.3.4...
telnet: Unable to connect to remote host: Connection refused

>From outside everything is ok:
Trying 1.2.3.4...
Connected to 1.2.3.4.
Escape character is '^]'.

Any suggestions, how to enable lan connects to 1.2.3.4:25 ?
Many thanks for any ideas.

Best regards,

Jan Gregor
