Is there any way to use SNMP to monitor traffic flow through an IPsec tunnel? I'm successfully capturing port traffic with SNMP but would also like to capture the traffic between our two sites via an IPsec tunnel.

Hi; I want to do monitoring from snmp service but I don't want to open snmp service to the all world , I only want to allow snmp to the specific ip adress. for this process; I am going to system -> administration -> snmp and activated the snmp service…

By default, the agent's port is 161 and the manager's port is 162, but many internet operators here in Brazil leave this port blocked, which makes it impossible to access the firewall's SNMP. How to change this default port?
