Pix 501 and Local Network Router (No VPN Needed)

Threaded View
Ok.. I have set up a 501 Pix, with a BEFSR81 Router. (sorta...)

I have the pix setup to where I can get out to the internet using the
4-ports on it , but...

I want to add the router between the pix and the pc systems for the
internet.  No go.  I have worked with the router, and the pix, tried a
couple examples (trying to remove what is related to vpn to another
location in most examples).

End goal, is to have the computers connected to the router, the router
to the pix.  I've erased and started over and over and over...
Missing something(s) really stupid I'm sure, but anyway, for now, here
is a pretty plane jane config that I went back to and at least does
get the pix ports out to the net, Now what do I need to do in order to
get the router in-between systems and pix?

I don't care about VPN at all right now, but I think I will use it
down the road.  A solution that won't be compromise future VPN use
would be great...  Thanks.

Re: Pix 501 and Local Network Router (No VPN Needed)
I don't know but you can start by getting rid of this:

fixup protocol dns maximum-length 512

Negate that. It's bad. Also, turn on your snmp and run something like
KIWI syslog to see what kind of errors are passed when you connect up
the router.

Thanks


Re: Pix 501 and Local Network Router (No VPN Needed)
Hi,

If you are putting a router in between the PC's and the PIX then the inside
interface of the PIX would have to be on a different subnet from the PC's.
Assuming you have done this - as the router wouldn't let you configure
overlapping addresses on it's interfaces - then you just need to add a route
onto the PIX to say that the PC subnet is via the router's interface...

In this example I have used 192.168.2.0 /24 for the PC LAN and 192.168.1.254
for your router's interface:

route inside 192.168.2.0 255.255.255.0 192.168.1.254

Thanks Martin, I appreciate your help.  My original message never
showed up on my end, and yours was the only reply (But it should do
the trick).  I appreciate your time as well - Xlat
