Not able to route the traffic to a particular webserver

Going to need a lot more information on this one.

What is your virtual setup? Is this one WebServer part of a pool, and other ones are working?

What monitor do you have on the pool/node? What response are you getting? Have you done a TCPDUMP to confirm connectivity? Has it worked before ?

thanks for your reply :), Our F5 is setup with 4 webservers and the traffic is not going to one of them yes the webserver is part of the pool and the other ones are working fine. The monitor that we have used for this is same as that of the other webservers. I did not get the TCPDUMP yet. Does bouncing the webserver help us in any way.

I suggest you have a HTTP(s) Monitor in use. Did you check Webserver Logfiles for Health-Check requests? Is an ICMP Health-Check working?

So it would appear from the information you've given us (Assuming that they're in the same subnet and all that niceness)

Its going to be a Webserver specific issue.

Don't know what service is running on, but if you run a tcpdump on the f5. Something like

tcpdump -I 0.0 host IP.AD.DR.ES and port 80

I'd hedge my bets you're seeing resets or similar coming back from the server.

Hi, sorry for the delayed reply, I will not be able to run tcpdump on the F5, but I got info like telnetting to the webserver with GET / is not giving any response, however if I telnet the webserver with GET /HTTP/1.1, Im getting the response, so do you think that it is an issue related to firewall.

Unlikely to be a firewall issue.

2 Things I would check:

1) Change monitor to GET / HTTP/1.1\r\nHOST:127.0.0.1\r\nCONNECTION:close\r\n\r\n
2) Check routing, maybe switch on SNAT Automap for a bit to see if assymetrical routing is an issue...
