Netsight can not poll from switch behind firewall

[Husam]

I am using default SNMP setting, for local switch everything is going well but for remote site I can discover all switches using SNMP default setting but I can not poll any information.

the connection between netsight and switches is over VPN and all ports are opened.

is there any special config should be done for remote site:

Thanks in advance,
Husam

same I can not poll any information.

Just to make it clear, I can discover all remote devices using default snmp also I can ping and telnet the device . But when I try to poll information for example interface summery, nothing is working.

please help!

Husam

Hi Husam,

could you please enable "redirect client/server snmp connection" and let us know whether that solves your problem.
