F5 as Default Gateway Routing issue
Hi All, I'm having an issue where a certain client needs to connect directly to a node behind F5 ie bypassing the F5.
The issue I have is that the node has a default Gateway of f5 and it receives a tcp reset after the syn, syn ack, I think its an asymetric routing issue. This is easily resolved by adding a static route on the node for this client to route the traffic back to the firewall essentially cutting F5 out of the communication. I need to know if there is a way of routing this traffic back through F5 without the need for a static route on the node?
After some research on this site I created an forwarding IP virtual server with a customized fastl4 profile to include loose initiation and close, also disabling reset on timeout and disabled keyless vlan as this suggested it may solve my issue but no joy.
this is what the tcpdump shows 11:35:40.383164 IP 10.1.1.22.48470 > 192.168.1.10.104: SWE 4242789294:4242789294(0) win 8192 11:35:40.383203 IP 192.168.1.10.104 > 10.1.1.22.48470: R 0:0(0) ack 4242789295 win 0
