Hello
I am trying to configure the server initiated connection on the CSM-S working in bridge mode.
As far as I was able to check, the SYN packets are leaving through the CSM. The SYN-ACK packets are coming to the CSM from the client vlan but, somehow, they are not passing the load-balancer.
I've already configured the direct-access vserver/sfarm and the communication initiated from the outside word to the server that is trying to establish a connection outside works fine. It failed in the oposite way.
If anybody knows how I could fix this issue please let me know.
Regards

Lucas,
is the SYN/ACK coming back on the different vlan than where the SYN was sent ?
Try to have only 1 gateway and make sure this is the one going in the same direction as traffic coming in.
CSM does not like asymetry.

Hello
The SYN/ACK are comming on the client vlan and the SYN was sent via the server vlan.
They are both bridged.

If the client and server vlan are bridged, you should not need a vserver/serverfarm for communication from client to server.
Could you try removing it and see if that helps.
What version do you have ?
Can you get a 'show mod csm x var'.
Thanks,
Gilles.

do you have static nat ?
You could try to configure the following
variable ROUTE_UNKNOWN_FLOW_PKTS 3

Hello
I apologize that I am replaying so late but I was on holidays.
I will check this value by the end of the week.

Unfortunately this command doesn't work in bridge mode. Below is what we saw:
