If you use pppoe, and your ISP blocks ICMP packets (many incompetent 
ISPs do so), you will need tp CLAMP MSS:

iptables -t nat -A POSTROUTING –s <your LAN network> -o <the eth port
used to go outside> -j SNAT --to-source <Your VALID TROUBLED PUBLIC
IP>

e.g
-A POSTROUTING -s 192.168.0.1/255.255.0.0 -o eth1 -j SNAT --to-source
66.94.234.13

to send/receive mails.
