Hello Eivind,

I agree with Hugh that sharing ports can not be done and you would need 
to use different ports.

In case you have the possibility to modify the Net-SNMP configuration, 
you should try the proxy option.

http://www.net-snmp.org/wiki/index.php/Snmpd_proxy

Using Ubuntu 12.04 as an example, something like this should get you 
started:

1. Configure Radiator SNMPAgent to bind to 127.0.0.1 port 1161
2. Optional: configure it to use SNMPVersion 2c
3. Add the following lines in /etc/snmp/snmpd.conf

proxy -v 2c -c public 127.0.0.1:1161  .1.3.6.1.2.1.67
view   systemonly  included   .1.3.6.1.2.1.67

After restarting snmpd and starting Radiator, this should work:

% snmpwalk -m+ALL -v2c -c public 127.0.0.1:161

This shows everything that public community can access

% snmpwalk -m+ALL -v2c -c public 127.0.0.1:161 .1.3.6.1.2.1.67

This shows just the accounting server subtree. This is the information 
that is available if you query Radiator directly (the port is now 1161):

% snmpwalk -m+ALL -v2c -c public 127.0.0.1:1161 .1.3.6.1.2.1.67

Thanks,
Heikki
