Unfortunately I don't have any suggestions on the proxy issue as I 
havn't used it as a proxy, but, 1.6.1 is VERY old now and has a lot 
of bugs that have been fixed in recent versions, including a few 
denial of service bugs that can cause the radius server to crash if 
sent malformed packets.

Why can't you upgrade to 1.6.7 ? One of the advantages of the newest 
versions is 'radrelay' which we use to do full bidirectional 
replication between primary and backup radius servers.

Staying with such an old version that has many known bugs, some very 
serious is a bit crazy IMHO :-)
