Re: Extended ACL rule..

UDP a subset of TCP? umm...
Please, make sure you read ROUTING TCP/IP VOL 1.
But frankly, this is described in any basic IP documentation. Maybe this is
so basic, that it's even not mentioned in ROUTING TCP/IP.

What I would recommend, is to download wireshark, and capture some packets.

Jitendra, you really need to see how the packets look on the inside, and
wireshark is a good tool to learn this.
