Hello
Now here's a problem I've never thought of before.
We have been given a net from UUNET. The first IP-address (.161) is used
by their router (which we have no access to fiddle with). I have
installed a firewall at .162 which will serve both as firewall and
trafic controller. My question is how to I make the public IP-addresses
accessible from the outside and still be located behind the firewall?
Like this
[Internet]--[UU-Router.161]--[Firewall.162]
I want to be able to put a machine behind the firewall on a public
IP-adress (.163) but still protected by the firewall. I was told that
this could be done in other firewalls by aliasing the NIC on the outside
to all public ip-addresses and then have the firewall forward these
packets to a computer on the inside. Like portforwarding but a whole
machine (all ports) on all protocols (under IP ofcause) (not blocked by
the firewall).
Is this possible with ipchains and some fancy packetrewriting?
Anyone have any tips?
