ICMP pinging.

Heya fellas,

I just noticed this last night after playing and configuring my PIX 501 for like 3 weeks. My problem is my LAN can not ping outside world. I can ping inside from outisde, but not vice versa. I did managed to get it to ping outside, but only if I added a specfic lines in my config, if by doing that my other service will not run(ftp,port 8080,3389,etc). Im going paste my config here, so you guru's can take a look whats really wrong with it. If I put these line back everything work, but we cannot ping outside of the LAN.

"access-group inbound in interface outside"( cannot ping outside, but all my serivces will run)

NOW THIS.

"199pix(config)# no access-group 103 in interface outside" "access-list 103 permit icmp any any echo-reply" (with this 2 lines, my LAN can PING outside, but none of my ftp,mail,web will run)
