[OpenSER-Users] authorization problems with multiple servers

Hi We have a problem with clients authorizing (whether for INVITE or REGISTER) against a pair of openser servers, served via either round robin A records, or multiple equal preference SRV records. The problem in a nutshell is client sends INVITE to server 1 server 1 replies with authorization challenge client sends INVITE with auth to server 2 server 2 doesn't like the 'nonce' value Now, this only happens via our nat proxy, as far as we can tell, so I think the problem lies there (and I have contacted the vendor of that system). However I wonder if there is any way to make openser work in such a setup, in case other client do the same thing (which IMO is quite a stupid thing to do) ... would the valid 'nonce' values need to be stored in the DB? Incidentally we are using mysql authentication and we are using usrloc in db_mode 3, with both openser machines pointed at the same mysql server. We're using a pretty recent openser SVN revision (dev15). Any tips would be appreciated. thanks -ben -- Ben Smithurst http://www.bensmithurst.com/
