IPSec Connection - Server con Amazon to main UTM to remote network with red device.

I have a UTM SG330 with firmware 9.703-3, I have made an IP connection with a server at Amazon. The network of my internal main office can ping the server and it responds, but other subnets such as the VPN pool and the network of a remote office that is connected to the main utm through a network device, when pinging the server from amazon they cannot reach. I really appreciate your suggestions to be able to make the connection successfully.

Hello Luis,

Thank you for contacting the Sophos Community.

Check this KB, this might help you, or this other one if you are unable to modify the IPsec tunnel most likely what is happening is that there are no routes for the subnets you are mentioning.

Hola Luis and welcome to the UTM Community!

When pinging from Amazon, watch the Firewall Live Log to see if there are blocks. You can put the public IP of the Amazon instance in the 'Filter' box to just see lines coming from there. See #2 in Rulz (last updated 2019-04-17) to understand why the answer is likely on the 'ICMP' tab of 'Firewall'.

Cheers - Bob
