ltm shows only half session in tcpdump
hi,
i have a situation where tcpdump on BIG-IP only shows traffic hitting the VIP(the 3-way handshake) but nothing between the LTM <-> back end server.As a result tcpdump on firewall after the BIG-IP shows no traffic hitting the actual back end server. There is SNAT in place to hide the Source IP on BIG-IP.If there is no traffic that appears in tcpdump between LTM<-> back end server could it be because somewhere between the two the routing for the SNAT IP is not in place? and hence the LTM doesn't bother to send the traffic to the server?
any help is appreciated.
thanks.
