Since SKIP protocol does no employ a session  
negotiation phase, the effect you mentioned should
be considered as normal behavior unless special 
logic is built into the product itself (note I did not say 'the Protocol').
 
When you change some server IP address, a 'remote' SKIP
ACL entry might became stalled.
If a remote SKIP ACL entry was of a 'Network' type and
just changed address fits into it's old subnet - you should not be in trouble.
If a remote ACL entry was exact IP address match - you must change
remote ACL to point on the new IP.
If a remote ACL entry was for so called nomadic host - you should 
just reload this entry to clear internal cache or wait until the 
cache entry is expired.
 
Other words, in worse case you will have to correct configurations 
on all machines used to talk SKIP with one with changed local IP address.

Subject: Does changing the localhost IP break SKIP?

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.
