Hi, That's true, but than you've just created 2 networks and thus 2 different broadcast-domains... so you will "route" between the 2 interfaces. I think (if I understand it good), it has to be 1 BC-domain, and that's just the problem.

I can think of a solution but as Tom has said it might not allow to route between the interfaces. But you can try it What you can do is provide smaller range of IP with mask. For example on Ethernet interface 0 you can provide IP address as 192.168.61.64 mask 255.255.255.248 ( it will give you a range of 192.168.61.65 to 192.168.61.70 ) and on Ethernet Interface 1 you can put IP address as 192.168.61.71 mask 255.255.255.248 (it will give you a range of 192.168.61.72 to 192.168.77 ) IP addresses on the Ethernet interfaces will not overlap with this arrangement but I am not sure about the IP routing issue. Anyone with a spare Router with 2 interfaces can try out and let us know.

The only solution I see is that you give eth1 "ip unnumbered eth0" (or reverse), then your both interfaces will be in the same BC-domain, but I don't see the use of it... Unless somebody else knows a solution...? regards, Tom -----Oorspronkelijk bericht----- Van: Paul Messer [mailto:[email protected]] Verzonden: maandag 16 oktober 2000 12:22 Aan: [email protected] Onderwerp: [FW1] Cisco 2621 Dear All, slightly off topic ..but I know where the expertise lays on this type of subject....... We have a Cisco 2621 router (not yet in use)...and we want it to serve our 4 site WAN. We have FW1 running on an NT box and the 2621 has two ethernet ports, one to plug the internal side of the firewall in to and the other to plug the local Basingstoke network into. Three of the remaining 4 serial ports are for the remaining 3 sites of our WAN. Firewall Internal Interface IP address = 10.10.10.10 2621 Ethernet 0 IP address = 10.10.10.1 (for historical reasons) When I try and give Ethernet 1 the ip address = 10.10.10.2 I get a message from the router stating that the ip address on interface 0 overlaps...does anyone know of any way that I can set the ip addresses on the ethernet port to be the same network i.e. a broadcast ? The only other idea I have is to give it another ip network and route between the two..is this the only way or are there any sensible solutions.... Currently we have separate routers for each WAN connection and the Firewall box plugs straight into our Basingstoke network switch which obviously adds a bottleneck in that every packet destined for the internet has to go via the Basingstoke network. Any help greatfully revceived......
