Access list

Sorry.

I meant I have 2 computers, A and B connected to one router.

PC A must be able to initiate TCP connections to B and be able to receive packets in response to its own connections.  

But PC B alone can't initialize TCP connections to A.

how do I configure the accesslist

Thank you

Hi AgeOfWars,
Create an access list which only permits established connections back to computer A :-
access-list 101 permit tcp any any established
access-list 101 deny ip any any

Then apply this access-list in the outbound direction on the interface computer A connects to.

Hi GrBlades,

I have 2 questions)

1)
Can you briefly explain the use of TCP and IP in the sentence. I know what they means but I don't really get it.

2)
Say, PC A is connected to Router port 1 and B is connected to router port 2. When a packet travels from PC A to PC B, the accesslist will activate becuase it is applied to port 1. my question is when a packet travelling from PC B to PC A, it will go through port 1, route to port 2 and to PC A, will the accesslist applied on port 1 be activated?
if yes, which will be the outbound and inbound port?

Thank you.
Ian

Thanks!
