Hi,
I'm trying to set up ip forwarding for two web sites on two different
servers using some form of port forwarding. The firewall is running
Mandrake 7.0, and I have ipmasqadm installed and functioning. I've read
that ipmasqadm portfw will not work for internal ip addresses, and that to
get around the issue one should use both portfw and redir, but I have been
unable to get that part working.
A little more background...
The web sites reside on two different NT boxes inside the firewall and use
192.168.x.x addresses. The web sites both lookup to 205.x.x.x addresses.
The two 205.x.x.x addresses correspond to eth0 and eth0:1 on the firewall.
I've configured ipmasqadm portfw to redirect the appropriate addresses on
port 80 to the appropriate destinations, and configured ipchains MASQ for
traffic going from the web servers back out to the internet. This is
working.
When I try to set up REDIR it complains that the port is already in use. I
had tried using REDIR without ipmasqadm portfw, but that was not completely
effective either. I could view the web site from some locations but not
others.
This is for an educational institution that also provides internet access
for the local community, and we need parents of students to be able to
access the web site whether they're customers or not. With ipmasqadm, they
can't access the pages if they're customers because they're on our internal
network.
Any help would be appreciated.
Brendan
