XG - cant ping/access the hosts from outside

Hi Cenk,

You need to configure port forwarding in the ISP router to allow the connections to the XG firewall. 

Thanks, 

Hey Sachin.

thanks a lot for your answer. Below you can see my forwarded ports from ISP router to xg. WHat am i missing? :)

Thanks a lot for your help!

Cenk,

Remove the alias IP 192.168.2.252 on your port 2 (WAN)

That's an IP in the same range as your LAN range, but on your WAN side. That doesn't make sense!

Hey,

Thanks a lot for the tip. Did it right away!

Any suggeastion regarding my ping/access problem to public ip?

To ping your WAN IP, you need to go to System > Administration > Device Access > Local Service ACL. Here select Pin/Ping6 for WAN zone.

I would only recommend to do that temporarily for troubleshooting.

For your access problem: in rules 10, 9 (and maybe also 7) change source to WAN 192.168.3.101

Good luck

I tried that also before but no success.

And, why i should be able to ping my other ISP public ip which is on another router but cant ping the other one?

I am really stuckedhere and hope for a help.

Thanks

Cenk,

For the ping problem: in the log viewer, add a filter "protocol is ICMP". Here you should be able to confirm if the ping-requests reach your Sophos XG or not. Don't forget that the ping-reply has to get back to your machine that sent the ping-request. Maybe that's blocked by the ISP router.

You can also try a tracert / trace route command. Maybe it's a routing issue...

Good luck

Hi,

i can confirm that i see ICMP requests for my public ip which error message says "message="ICMP packets with invalid ICMP type/code."

What is wondering me is that i can ping my public ip from my LAN without problem. Since we can see the ping requests at XG, can it be that XG is not answering to the requests because of one missing route or something?

Thanks a lot guys!

Hi Cenk,

You have 2 WAN interfaces. Are both set to Active? Both have the same weight? (Configure > Network > WAN Link Manager)

Secondly, can you go to Monitor&Analyze > Tools > Traceroute and tracert 8.8.8.8 once via Interface 2 and then via Interface 4
Can you paste a screenshot of both results? Or you can PM me the screenshots

Thanks
