Error on "when CLIENT_ACCEPTED" IRule

Sep 5 15:42:11 F5-Prod err tmm[7623]: 01220001:3: TCL error: /Common/IR_TCP_TimeOut - no serverside connection established (line 1) invoked from within "TCP::server_port" ("1423" arm line 4) invoked from within "switch [TCP::local_port] { 1423 { .......

i do not see TCP::server_port in the irule. is it complete irule?

Yes this is the complete IRule.

I get the example here: https://devcentral.f5.com/wiki/iRules.IP__idle_timeout.ashx

When I replace "switch [TCP::local_port]" by "switch [TCP::server_port]" it doesn't work as well.

It was just a test, because I don't really understand why there is an error.

I suspected a bug with TCP::local_port ...

i did not get an error.

So no bug :-), but the problem still there. When a connexion occur with port 1423 there is the following error:

Sep 5 15:42:11 F5-Prod err tmm[7623]: 01220001:3: TCL error: /Common/IR_TCP_TimeOut - no serverside connection established (line 1) invoked from within "TCP::server_port" ("1423" arm line 4) invoked from within "switch [TCP::local_port] { 1423 { .......

I have built the following simple IRule. It's working fine but the timeout is increased for all flows (no filter on port).

when CLIENT_ACCEPTED {  
set the TCP idle timeout for the client to 3600
IP::idle_timeout 3600
    }   
when SERVER_CONNECTED {  
set the TCP idle timeout for the server to 3600
 IP::idle_timeout 3600
}

Hello,

The error occurs because the Big IP receive some UDP traffic. The script does not managed UDP port. so a filter must be added at the start of the script.
