I am setting up a Dachstein LEAF firewall connected to a DSL modem. The
modem has a static IP and does NAT and port translation. I am connecting
the inside of the DSL modem to my LEAF box and want to do NAT and port
translation again. I have changed the inside IP to match our network and
have successfully figured that out. And the Inside of the DSL modem is
10.0.0.254 and the outside of the LEAF is 10.0.0.1 It will be a "double
NAT" but that was about the only way to use LEAF with the DSL (I got that
answer via this forum.) Bridging on the DSL modem is not an option.
But 1 problem:
Some of the Port translation doesn't seem to be working completely. In the
network.conf file, I have opened the
EXTERN_TCP_PORTS="0/0_pop-3 0/0_smtp 0/0_500" #the 500 is an unique to us
port translation
Then in the Port Forwarding section I have
INTERN_SMTP_SERVER=<our smtp server>
INTERN_POP3_SERVER=<our pop3 server>
INTERN_SERVERS="tcp_10.0.0.1_500_<internal IP_port>
The problem I get is the POP3 doesn't work unless I add the
INTERN_WWW_SERVER=<ip> in the port forwarding. The error on boot is
IP filters:pop-3: Host name lookup failure
portfw:illegal destination specified
And when I add the INTER_WWW, I have found that regardless of what IP I put
for the POP3 server, I get the IP of the web server. i.e. if I set the
INTERN_POP3=193.0.0.10 and the INTERN_WWW=193.0.0.5, in the firewall rules
for port FW (via the weblet-Firewall Rules) the rediraddr for the POP3 is
the same as the WWW, in this case 193.0.0.5. The SMTP and the port 500 have
the proper rediraddr.
