ASA session problem

Hi Sir,

I ask question about session of ASA.

I want to access from my host to Destination host.

Example.

+------------------+

| Destination host |

+---+--------------+

|

+---+----+

| Router |

+---+----+ | Other network

| |

+---+----+ +-----+

| Switch |-----------| ASA |

+--------+ +-----+

|

+---+----+

| My host|

+--------+

The default gateway of my host is ASA.

[Outgoing]

My host -> ASA -> Router -> Destination host

[Incoming]

Destination host -> Router -> My host

[Session flow of ASA]

1st. The ASA received packet of 'SYN' flag.

2nd. The ASA doesn't received packet of 'SYS + ACK' flag.

3rd. The ASA received packet of 'ACK' flag.

I think,

This problem is that ASA can't received packet of 'SYN + ACK'

I want to resolve this problem that doesn't change network topology.

Best Regards

Ryusuke.

Re: ASA session problem

Is your router and ASA on the same network?

In that case when the return traffic arrives at the router, it will arp for the host (as it is on the same connected network) and send the traffic directly instead of sending it to the ASA
