Hi there,

 

using an ER6020 to provide Internet access, I have to filter a port (5060) AND an IP address (the VoIP provider), because we are experiencing a very important lot of connection attempts on the PBX and I want to be able to block them upstream of the IPBX.

 

I think I'm doing something wrong because port 5060 keeps passing connection attempts from all IP addresses (not just the VoIP provider as expected)

 

The PBX is configured as a virtual server in the NAT rules with port 5060 UDP, as usual.

 

I may have searched the documentation wrong, but I would like to know how to completely block a port unless it comes from a single IP address.

 

Thanks in advance

Jérôme

Thx for the link.

 

I had already done this procedure, but the PBX server continues to receive connection attempts on port 5060 even though I restricted it to the trunk provider's IP address.
My goal is for the router to block them BEFORE they arrive on the PBX and go into the blacklist (and send me 200 alert emails per day, as currently)
