filter-id help

[Dana Teague]

I am running freeradius 1.0 . My server has been running for several years 
and has worked great authenticating users with a PIX and dialup servers.  We 
are adding a watchguard firewall.   Freeradius needs to send the watchguard 
the following filter-id on successful authentication: IPSEC_RADIUS.  It 
appears to just send RADIUS and causes the authentication to fail.   I know 
this is simple but I am having trouble getting this to work.

Please help
Dan
