Dear All,
We have an unusual problem. We have just installed a rh7.1
firewall with iptables 1.2.5, we have multiple virtual ip's on one nic (all
have the same mac) connected to a lan which is then piped to the internet
through another section of our network to the internet.. The firewall works
just fine if you are on the lan that the nic is on (X.X.56.X), but if you
attempt to connect to this network (x.x.56.x) from outside the connection
fails, when just one ip is set it works just find from everywhere. we have
traced the problem to a cisco 7500 router (which we have no control over)
and the mac address of the nic, if we could have multiple ip's and multiple
mac address for the ip's I am sure it would work. I tried to change the mac
of the card (eth0) which worked, then I tried to change the mac of the
virtual ip's (eth0:1, eth0:2, etc) which just changed the mac of eth0.
Does anyone have any suggestions for a solution???
Has anyone had the same problem??
Thanks
Shaun
