Setting The Dude 6.48.3 and same devices are not properly responding do SNMP
The main problem is on the picture. Same source device, same target.
Same Dude server but once it is connected via public IP 194.x.y.z and the second is vi VPN.
Removing, adding ... reprobing ... same problem
Server on 1100AHx4Dude, Probed device is RB 4011iGS+ but other non 4011 device behave same way.
You do not have the required permissions to view the files attached to this post.
Of course I did. The log is from the same device monitored from one Dude server
Lines 1,2,6,7,8 are log of communiction with Dude via public interface.
Lines 3,4,5 are log of "talk" made by "local" interface = VPN connection
From you reply, I can deduce you want use v3 (read/write) just because "last version, better version" reasoning.
Actually if you don't need it (because you know what it is for), ALSO for security reasons, better use the v2c (readonly) which also uses less resources on the machine
