Issues with VPN to AWS

laurence64 — Tue, 17 Aug 2021 16:20:48 GMT

I appreciate this is an odd one but I have a little bit of an issue with my home setup, I have a pa-220 behind a sky router, the issue is that if I am coming from the inside network i.e mgmt interface that traverses the inside zone to make it out then I can ping anything I want, however if I am trying to source the ping from the external interface then it fails, this is causing the issue above where I cannot get a vpn up between me and aws as there is never a reply received.

Any help would be greatly appreciated.

Hello there

I have a PA220 and pings do work for me. You would need to confirm you have a rule that allows ping FROM the outside interface as shown in my screenshot below:

You should look in your traffic logs and see your pings failing, due to hitting a rule.

If you do not see your traffic, then perhaps you are not logging your traffic on the Intrazone rule at the bottom of your configuration.

What other questions can we answer for you?

Hi @S.Cantwell

The problem, unfortunately seems to go much deeper than I feared, there is an issue where traffic originating from the external interface of the firewall cannot it seems make it to the Gateway, although traffic from the inside zone can, I am talking it through with TAC as well as the upstream provider as this did work previously.

Thank you for your reply though and you are, of course, right that I should check there for the logs and make sure the traffic is allowed.
