One connected with LAN switch, 2nd with Dallas router's ethernet and 3rd with Texas router's ethernet.following is the output of my PIX's sh run..

I uploaded your config to a pix and from the inside was able to ping and telnet to the dallas router. This is a good indication I should be able to reach clients beyond that. As long as the rest of the network is working correctly.

You may want to do some trace routes from the inside to the other networks and from the other networks to the inside. Verify you have routes coming back from those internal networks as well.

On Dallas and texas network routers, there are route to my dallas and texas interface network IDs.I think there is no need for the route to my internal network ID because NAT is enabled.Am I right or wrong?

right.

Turn on logging on the pix. Do trace route and pings from both sides and if traffic is being denied you will see it in the loggs. If your not getting any denies you may want to capture traffic on the pix interfaces to see if the requests and/or reply's are acutally getting to the pix.

I tried to use logging on command. But there is nothing display on console window. Can you tell me the command with witch I can monitor passed and denied traffic from my PIX firewall?

I want to know the command which will enable logging for only denied or passed traffic from a particular source or to a specific destination for inside and outside....on PIX515e

logging on

logging console errors (connected via console cable)

logging monitor errors (connected via telnet/ssh, must also enable terminal monitor)

logging trap errors

logging host inside IP_ADDRESS (log to syslog on inside)

Link on how to capture:
