Extended ACL question 3

ACL 1.access-list 115 permit tcp 192.168.1.0 0.0.0.15 host 192.168.2.2

ACL 2.access-list 116 permit ip 192.168.1.0 0.0.0.15 host 192.168.2.2

was trying a simple configuration , the second one worked,the first one
with tcp did not work, is tcp used only when I use port numbers ?

You use:
permit tcp for TCP traffic
permit udp for UDP traffic
permit ip for TCP and UDP both

tcp traffic = ip+port number ?
so if i wanted the first acl to work i would have to use
> access-list 115 permit tcp 192.168.1.0 0.0.0.15 host 192.168.2.2 eq 80 ---for example

I just cannot use tcp keyword without a port number..

What were you doing to test the ACL with tcp?

You cannot implement an ACL that filters TCP or UDP without a port number, there would be absolutely no point to this.

Thank You James.

Quickman, was using wild card masking to allow selective access to a server , IP was enough.
With TCP now I am doing filtering selective access like ports 80 etc
like below

access-list 111 permit tcp 192.168.1.16 0.0.0.15 host 192.168.2.2 eq www

Thanks You everyone
