Help Debugging connection to ip?



  • Hello,
        I am unable to connect to the ip 66.70.234.210

    Two days ago, before installing the pfsense box I could
    Using 3rd party websites, I can ping that address

    From the pfsense box I always get:

    
    PING 66.70.234.210 (66.70.234.210): 56 data bytes
    
    --- 66.70.234.210 ping statistics ---
    3 packets transmitted, 0 packets received, 100.0% packet loss
    
    

    In the firewall log I see:

    
    PASS Apr 6 15:32:13	► WAN	let out anything from firewall host itself (1000110341)	  66.74.215.113	  66.70.234.210	ICMP
    PASS Apr 6 15:26:32	► WAN	let out anything from firewall host itself (1000110341)	  66.74.215.113	  66.70.234.210	ICMP
    PASS Apr 6 15:23:19	► WAN	let out anything from firewall host itself (1000110341)	  66.74.215.113	  66.70.234.210	ICMP
    
    

    (the above has a destination filter for 66.70.234.210 set)

    I am at a loss of how or what tools I would use to debug this.

    Any help would be appreciated

    notes:
    I am using the following packages:
    Avahi
    pfBlockerNG (already checked the logs and nothing)

    If your sending it out your wan, and you get no answer.. Either they do not answer ping or your pings are not getting there.

    Seems to answer ping

    ping 66.70.234.210

    PING 66.70.234.210 (66.70.234.210) 56(84) bytes of data.

    What does your traceroute show?

    when I hit that IP via http it comes back
    mining server online

    What are you trying to do exactly?

    Those seem to be OVH ips, so their DC.. So some VPS or dedicated box?  Looks like those IPs are failover?

  • I am attempting to connect to:

    xmr-usa.dwarfpool.com

    There are four ips associated.  I seem unable to connect to any of them.  I decided to pick one to debug as a method of simplifying my problem.

    I am able to connect to xmr-eu.dwarfpool.com.  However, this comes with a 220ms latency, which means I am wasting 1/4th a second every block switch.

    The tracert result is below:
