I've search the INTERNET for 5 days now and late into the evening, but
I'm
totally stumped in resolving my problem, so I would appreciate any
guidance from the experts. I've configured as per the many guides I've
found and have a basic understanding of how this all works, but there is
no information anywhere on how to setup the Users / Client details for
freeRADIUS.
Did you try reading comments in users file and clients.conf ie. files you
were about to change?
First THANKS for replying...
I did, but still cannot work out what I'm doing wrong on this as there is so
many guides and different ways of doing things, or thats how it seems.
Everything authenticates ok and the correct IP is allocated now, but I'm not
able to BROWSE any sites and cannot even ping the ip address given to the
PPP adatper. I can only access the VPN, but none of the traffice seems to
be routing correctly. Can you offer any further supports, please.

The problem, I'm facing is the allocation of IP address / GW / DNS by
freeRADIUS for the VPN connections coming onto my server.
my service PrivateIP address is 19x.xxx.xxx.190
I've iptables setup to forward all NAT traffic through the PRIVATEIP, but
allocation of a GW of 10.0.0.1 and a Client IP of 10.0.0.200
However, when I connect and freeRADIUS authenticates me SUCCESSFULLY. I
get given a IP of 192.168.2.82 from the test_pool, but pool range-start =
10.0.0.100 range-stop = 10.0.0.199 which is totally different to the
address allocated by the pool. ANY IDEAS?
Was test_pool once upon a time in 192.168.2.x range? When you change the
IP range you need to delete db files. This is clearly stated in the ippool
module ie. the file you have changed.
I did not delete this, as this was the first time test_pool was used,
however this proved to be the issues and I thank you for that. So it must
have come in as part of the RPM.
