I have a google cloud system running on subnet 10.128.1.0/24 and a remote network on 10.173.2.2/23 with a google VPN IPSEC tunnel up and running.



I have the google remote network set to 10.173.2.2/23, and the local IP ranges 0.0.0.0/0 with the reciprocal in the remote site. The intention is to force all network traffic from the remote server through the VPN.



I am able to ping etc to the local LAN side of my google server (10.128.1.2) but I can't get to its public IP port (or any public IP).



Is there an easyish way to setup a google VPN tunnel that will route all traffic to the public IP on my servers, or the web in general?



Cheers

  • Can you provide more information on your use case? My understanding is that you are trying ICMP packets (originated in your premises) to get in the tunnel. Then reach the VM and have a packet reply coming from the external interface back in the tunnel? External IPs on GCE VMs are an abstraction that is performed by Google network (If you list the interfaces in your VMs using “sudo ifconfig -a” you will only see an internal IP interface and a loopback).

  • That been said, even if the VM had an external IP directly attached to it, some routing could have to be defined in the VM per se, so that packets from the external IP could be send via the internal one. You might want to use “traceroute” on different check points to see how the routing is being done.
