Hi ALL !!

I need to connect from a host (192.168.8.139)in the lan to host
192.168.1.15 so I put acl like this: ( I added the first line )

access-list 111 permit tcp host 192.168.8.139 any
access-list 111 permit tcp 192.168.0.0 0.0.255.255 host 192.168.8.2 eq
telnet
access-list 111 permit tcp host 192.168.8.7 any
access-list 111 permit tcp 192.168.0.0 0.0.255.255 any eq www
access-list 111 permit udp 192.168.0.0 0.0.255.255 any eq domain
access-list 111 permit tcp 192.168.0.0 0.0.255.255 any eq 443
access-list 111 permit tcp 192.168.0.0 0.0.255.255 any eq 5900
access-list 111 permit ip host 192.168.8.198 any
access-list 111 permit ip host 192.168.8.199 any
access-list 111 permit icmp any any echo-reply
access-list 111 permit icmp any any echo
access-list 111 permit icmp any any source-quench
access-list 111 permit icmp any any time-exceeded
access-list 111 deny   icmp any any
access-list 111 permit tcp any any established
access-list 111 deny   ip any any log

take a look also at line 3 of the acl this host is the internal mail
server, from that mail server when I try to connect to host
192.168.1.15 there is no problem !!! so I made a similar entry to
enable connection from my host (192.168.8.139) but It doesnt work !! I
know its a problem of the ACL beacuse when I remove this ACL (which is
applied to vlan 1 BTW) the connection works!!

please help !
