Hi,
It could be caused by a number of different things, here are a couple of tips that can hopefully help you isolate the problem;
- In the B box, do you have any entries in the TMOS arp table? (i.e. can the box see its neighbours? - "tmsh show net arp")
- Can you reach box A over different interfaces? (e.g. internal / external / ha) this again to confirm that box B does have network access.
- Can you reach the gateway from box B and can the gateway reach you?
- Have the same routes been configured in box A as in box B? (in CLI; "route -n" and "tmsh show net route")
- Have any of the self IP's been accidentally configured on "traffic-group-local-only", rather than the floating traffic group?
- Are any of the virtual servers using the IP address of any non-floating IP's?
- If traffic is coming in, but not going back out, check the routing on your backend servers and/or SNAT configuration.
These are just some ideas from the top of my head. Hope there is something useful in here.. ;)
