I've got a 501, with nat(inside) and global(outside). Something is preventing web browsing, ftp and icmp traffic. with netstat I can see the connections established(telnet to port 80 of external web server, ftp) but never see banners or login prompts. I've tried some with access lists and get icmp back and forth but nothing else. Even tried (http://22.214.171.124) in a browser with no luck. Anyone have ideas why?
this is my config:
nat (inside) 5 0 0
global (outside) 5 interface
-with no access-lists i get nothing in or out
but with permit any tcp,udp,icmp,ip i get the symptoms above.
I've seen something in an article about needing to have a ptr record for the external int.
Any help is appreciated.
