Accessing Droplets in VPC via Private Network After Connecting to Outline VPN

I used the digital ocean guide to setup an Outline VPN droplet and I’m able to connect to it with my external IP correctly showing the droplets IP once connected.

However I’d like to be able to, but can’t connect to any of my other droplets in the same VPC via there private network IPS.

Curious if there’s additional configuration I need to do to accomplish this?

I am able to access the droplets via there external IPs.

I’d prefer though to use their private ips so as to not have the network traffic between the droplets and VPN droplet count against our quota.

Any help would be appreciated.

Base on my experience. If you are setting OpenVPN and you would like to access other droplet resources in the same vpc, you must configure the following in /etc/ufw/before.rules

# NAT table rules
# Allow traffic from OpenVPN client to eth0 (change to the interface you discovered!)
-A POSTROUTING -s -o <eth0 OR eth1> -j MASQUERADE

Had the same issue when I followed digital ocean’s instruction. I had to change eth0 to eth1 then I was able ping and ssh to other droplets in the same vpc network.
