Hi all.
I am replacing my company router with a Cisco 831. basic configuration was done, but SMTP not working well.
Here's my case:
[internet]----[ADSL modem]----[Cisco 831]----[192.168.0.x]wan: 61.x.x.x
8 static IP 60.x.x.104 - 60.x.x.111All internal IP(192.168.0.x) use the WAN IP to access the internet.
First problem, when I try to test the SMTP server (192.168.0.10) from home. There are no reply at all. I know that telnet of windows not work, I tried putty raw mode, also no reply. however, http work.
Second problem, how can i set route so that my SMTP server ( 192.168.0.10 ) use the dedicated static IP (60.x.x.106) to send packet out? Some server's junk mail filter may treat incoming mail as spam if the server IP not match...
Here's my configration. Please suggest and Many THANKS!
