      Hi,

      I have a provider I am setting up a BGP connection with. The neighbor IP address is 169.254.169.254. I can ping this IP address without issue but the connection from this host back to the firewall is being blocked;

      Nov 21 10:04:08 WAN Block IPv4 link-local (1000000101)   169.254.169.254:51155   45.63..:179 TCP:S

      I know this is a link-local address and cannot be routed, but i am not routing i just want to accept this connection at the firewall to the openBGPD service.

      This worked for a short period of time early in the configuration stage but I cannot get it past the firewall now.

      I am using this to get an IP from the provider that i can float between 2 front end firewall's for redundancy. If you can suggest a better solution i am all ears too.

      Kind Regards

      Andrew

        APIPA link-local traffic is blocked by default because it usually is not traffic that should touch a firewall since it can never flow through a firewall.

        If you must accept that traffic, then:

        1. Make sure you have bogon blocking disabled on WAN, since that will block it
        2. Disable the automatic rule to block it

        Diag > Command Prompt, PHP Exec:

         $config['system']['no_apipa_block'] = true;
         write_config("do not block APIPA traffic");
        

        And then run a filter reload from Status > Filter Reload
