Don't know if this question is appropriate here, but here goes!
I want to configure the Mandrake Single Network Firewall in my LAN. We have
cable-modem access (cisco router) with a fixed ip address (212.51.61.xxx)
Internet access is acquired with a second ip address on the server/gateway
212.51.61.xxy) connected to the cisco router
We want to run various servers (an IIS/NT4 box and Linux-Mandrake)
We use a LAN config... 10.10.10.1 etc. connected to a second NIC on the
server and a switcher.
Present setup:
Internet <----> ROUTER (212.51.61.xxx) <-------> NT Server NIC 1
(212.51.61.xxy)
NT Server NIC
2 (10.10.10.1) <-------> Linux/PCs(10.10.10.n)
(Windows NT is running WINROUTE lite to handle portmapping)
Desired:
Internet <----> ROUTER (212.51.61.xxx) <-------> Linux FIREWALL NIC 1
(212.51.61.xxy)---->All servers/PCs (10.10.10.n)
Question: Is it absolutely necessary to have two NICs in my firewall box?
One for the outside connection (212. etc) and another to handle the LAN
(192.168. etc)? Or can I manage the entire steup with one NIC?
Thanks, in advance for any advice or direction to some documentation on
configurations for Firewalls
