Currently we have a mail server sitting on 192.168.1.2 and we have the following static nat
ip nat inside source static 192.168.1.2 25 (external ip) 25 extendable
This works fine, for forwarding smtp from the dialer to the mail server
however vpn client connections can only telnet to port
25 on the mail server by telneting to the external ip port 25 which port forwards to the mail server as per static nat.Is there a command i could configure so the vpn client can telnet directly onto port 25 of the mail server internally? so i can issue the
command telnet 192.168.1.2 25
The clients are using an address pool assigned by the router.
They can telnet to 192.168.1.2 110 (pop3) etc but not 192.168.1.2 25 (smtp)
is this because smtp is port forwarded from the external public address to the internal mail server address?
Any help would be greatly appreciated as its driving me crazy slowly
