Hi there,
I recently got a business connection from my ISP with a few static IPs. Through the 951G (v6.22), I’ve used NATing to link some of the public IPs with some private IPs. I also setup hairpin NATing, and this all works fine.
Just today though, I noticed that when I try to connect to a VPN from a local machine that has a public IP NAT’d to it, I loose all network connectivity from it. The VPN is located outside of my LAN, and I seem to be able to connect to it correctly. Once connected though, there is no further network connectivity and only pinging 192.168.0.1 succeeds, I can’t even ping the VPN gateway IP.
I presume I’ve made an error in my configuration. Has anyone come across this situation before, any suggestions?
I have included some details about my setup below -
Network setup:
/-------- Machine 1 (192.168.0.2 -> 1.1.1.2) with OpenVPN
WAN ------ MikroTik (192.168.0.1) -------/
public IPs: 1.1.1.1 \
1.1.1.2 * And more systems...
etc.
