I'm experiencing 'request timeout' when trying to ping external destinations from my network. The issue occurs when ACLs are enabled on my router. It's perplexing as to why this happens. Any suggestions or insights on resolving this issue would be greatly appreciated.
Here my network (its for school) :
So basicly i've been asked to denies tcp connection from outside but allow from inside (sorry for english i'm French)
R_Int config :
FAI config :
Thanks in advance.

I have tried other ACL conf for access-list 102 like :
access-list 102 permit tcp any 201.49.10.0 0.0.0.255 established
access-list 102 deny tcp any any
or :
access-list 102 permit tcp any 192.168.0.0 0.0.0.255 established
access-list 102 deny tcp any any
And as always when the acl is not here i can access my server web but when i put the acl i have "request timeout"

Ping doesn't use TCP, so you're probably (I haven't really analyzed what you're doing) are effectively blocking it. Also don't forget an ACL ends with an implied deny all

I'm now confused. Understand you only want to allow TCP outbound, but your OP notes issue with pings. So, only TCP outbound allowed, and if so, what's the issues with pings? (Again, if you ping inside to outside, ping is not TCP.)

Hello, ty it was a misanderstanding from me basically i was thinking ping is include in tcp so i made so changes :
access-list 102 permit tcp any 192.168.0.0 0.0.0.255 established
access-list 102 deny tcp any any
access-list 102 permit ip any any
and now it ping well so my problem right now is :
i cant connect to my Web server (S-Web) with my internal network (192.168.0.0)
