How to make server responds with virtual IP instead of physical IP
It appears that the client (server1) starts communicating with the virtual IP on the NFS App server, but for some reason, the App server is changing to its interface IP during the conversation for some of the UDP connections. The firewall will not allow this as it thinks that the connection has been hijacked by a different servers.

Re: How to make server responds with virtual IP instead of physical IP
I'm not sure to have understood well the problem, I understand the problem is the following:
on NFS client when mounting filesystem/s from NFS server it's using the physical IP address instead of virtual IP which should be the expected behaviour. And I guess you're using the name to mount.
If my statement is correct, I think the point is about the resolution. Try nslookup on both physical and virtual IPs, which name are you using to mount NFS filesystem/s?
Ciao,
Fabio

Re: How to make server responds with virtual IP instead of physical IP
have a look at this:
http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1174680
you may try adding NFS_TCP=1 and restart nfs.server daemon and run
ndd -set /dev/ip ip_strong_es_model 2
not tested, but hope it helps.

Re: How to make server responds with virtual IP instead of physical IP
just to clear my previous post.
When I suggested checking IP addresses by nslookup was not because I think the problem is about nslookup or IP addresses are not correctly configured.
I'll reformulate my question: on NFS client which name are you using to mount NFS filesystem/s?
Best regards,
Fabio
