It has been a while since I used the CSM and I am getting a little confused with NAT
I am wanting to create a loadbalanced VIP so Servers on subnet A can access LB to 2 others servers on Subnet A. Now obviously i need to do some Source nat to ensure the servers dont just cut the LB out when they respond to the requests. Hence I configured the following; but I can't see any arp for the VIP address on the server VLAN.
Since the VIP is on a different range as the servers, then, not having an ARP entry for it is expected. The servers assume that the VIP is on a different subnet, so, in order to get to it, they send the traffic to their default gateway.
Your configuration looks fine, so, if you attempt a connection to the VIP from one of the servers, it should work properly
Still no joy, I can ping the VIP, I can telnet to the servers on port 8081 direct. I see the VIP taking traffic and it says it is forwarding out to a server i.e in the counters however I never see the packet arrive at the server???
Strangely when I do;
sh mod csm conn vserver GAS_8081
prot vlan source destination state ---------------------------------------------------------------------- In TCP 895 172.30.60.41:34805 172.30.60.41:8081 ESTAB Out TCP 895 172.30.60.41:8081 172.30.60.41:34806 ESTAB

I get the above, i.e I dont see the packet going to the actual servers??
However i get the following while trying to connect;
trposr02#sh mod contentSwitchingModule 13 vservers name GAS_8081 det
