Does changing the localhost IP break SKIP?

[Ron Beck]

I've got 16 servers worldwide running SKIP on Solaris 2.5.1  Last week one of the system "caretakers" overseas changed the IP address for two of the servers.  Now the other 14 can't connect unless I delete the each machine's entry in the acl.hme0 file using skiptool.  The two servers whose IPs changed can still talk encrypted to each other both over the front side network (WAN) and the 5 foot patch cable that makes the backside network for NFS.  I've snooped the front side network to determine if any of the routers were blocking port 57, and they aren't.  There is no connectivity problems between these machines and the comm path is allowing all necessary packets to pass through.  The question is:  Does changing the IP address of the local host affect the machines ability to encrypt between hosts?  I don't think that's the problem since the two machines are encrypting between themselves, but I have no other idea what it could be.
