Hi folks,
I have 2 ISP Inet connections.
1 Inet I (eth0) use have used for everything (SMTP
server, MASQ for local network)
I got the 2 INET (eth1) and made some
changes:
They both have MASQ:
iptables -t nat -A POSTROUTING
-o $EXTERNAL_INTERFACE_2 -j MASQUERADE (2 Inet)
iptables -t nat -A POSTROUTING -o $EXTERNAL_INTERFACE_1 -j MASQUERADE (1 Inet) I changed default route to eth1
and put some additional route:
ip route rep default via ext_ip2 dev eth1
ip route add 1.2.3.4 via ext_ip1 (eth0) And now I'm having a problem with my email server
(Lotus Notes on Linux).
It can send emails via SMTP but cannot use
encrypted Lotus connection and receive emails as well.
iptables -t nat -A PREROUTING -i
$EXTERNAL_INTERFACE_1 -p tcp -d $EXTERNALIP_1 --dport 25
\
-j DNAT --to-destination 1.2.3.196:25 # Lotus Notes Encrypted connection (tcp 1352) port
forward from eth0 to internal ip 10.105.105.196
iptables -t nat -A PREROUTING -i $EXTERNAL_INTERFACE_1 -p tcp -d $EXTERNALIP_1 --dport 1352 \ -j DNAT --to-destination 1.2.3.196:1352 And how to route with ip route command
that email server have to use not the default route (eth1) but
eth0.
What I need to configure more to get working back
my email server?
Thank you in advance
