| I have a Pix setup using 10.2.1.1/16 as the inside address. This Inside address is connected directly via crossover to a 3640 e1/1 interface.
On the 3640 I also have configured a Fastethernet port to 10.2.1.100 as the default gateway for my lan?
My question is should my PIX E1(inside) address and the 3640 e1/1 address be on a different subnet than the fastethernet subnet?
Example I will set the ip address inside 10.3.1.1 255.255.0.0 on the pix
On the 3640
if)# ip address 10.3.1.2 255.255.0.0
The reason why I ask this question Is because I'm receiving overlapping address errors on the 3640? | |

| You and 007 are working on the same project, no?
Yes, you need to put these interfaces on different networks, otherwise the router isn't going to route between them (and it has to route between them since they're not phyisically connected).

| Woops!
That was an indiscretion, MadChef 
Maybe the two parties don't know about each other, and we are all annonymous, aren't we?

| Stickman,
You do need diff subnets to connect the two.
Here is how I set up my network with my pix. I hope this helps in answering your question. My PIX has 2 interfaces. I connected one to a 1000 series router (an old one). On this router I have s0 directly connected to my T1 line. I also has e0 connected to a small hub in the up link port and e0 on my pix is connect to the same hub. This is my external network. It has vaild external IP address and I put things on that can't be filtered through the firewall. On the PIX I then have e1 connected to my switch's uplink port, this is my internal network. My pix is providing my NAT and all my clients point to it as its default gateway.
I hope this helps | |

| Call me crazy, but I find it odd that 2 people ask about identical questions within a couple of hours of each other. Both were even receiving similar errors. Maybe it was coincidence, but I doubt it. They're still anonymous. They're just anonymous together.
Sorry if that worried someone.
