routing blunders

[matthew.bauer]

hey all,

I am at a lost. got a 501 out of the box 6.3.3. assign it an public ip address XXX.XX.XX.13 and its private ip 10.1.25.254

the public interface is connected to a 2600, eth0 ip address is one of my public ip addresses XXX.XX.XX.254 and se0 is 172.XX.XXX.157, which is provided by my ISP. On the inside I have a Cat4006, IP 10.1.254.254. Here is where I get confused. Before I got the 501 i could tracert ip address on se0 (icmp was enabled). From the 501 I can ping et0 of the 2600, but I can't get any traffic to go outside. I tried http, dns, ftp. I have left ACL's as is, which to my understanding is all traffic outbound is allowed.

before I started I tracert some ip address and could follow to se0

now when I tracert it stops at the cat4006, it timesout there.

I am getting confused on my routing statements

on the cat4006 i define an "ip route 0.0.0.0 0.0.0.0 10.1.25.254" so that all packets no for my network to go to the private ip of the pix. (is that correct)

I then tried to set a route in the pix for the inside interface to route 0.0.0.0 0.0.0.0 to XXX.XX.XX.254 (is that right) I don't think that it is. I can't figure out how the routing should be accomplised. Do I route the outside interface to XXX.XX.XX.254? Right now I am trying this on a 501, but In a couple of weeks I plan to use a 515e

any help would be appreciated

S.O.S.

Thanks

Matt

Hi,

Your default route from CAT swich is correct, that is pointing to PIX's private IP. But on the PIX there is no default route. you need a statement like

route outside 0 0 xxx.xxx.xxxx.254 (the ip of your router)

Ping or traceroute may not work, unless you allow them in from outside using access-list. but other statefull protocols e.g http/telnet should work.

Thanks
