Help with wireguard configuration

RouterOS General
1

Hello,

I've been successfully using wireguard for a few years now, running it on a dedicated VM within my network. The only configuration needed in my router was to NAT the UDP port to my vpn server.

I recently decided I'd like to try running wireguard on my 5009 and then I can eliminate the vpn VM.

I've successfully configured the WG on the Mikrotik, and a peer for my phone and the tunnel appears to work, although I cannot seem to access the internet or any network node on my network.

Here's how I was trying to set it up:

Router IP is 192.168.88.1

WG IP 10.0.0.1

Peer IP 10.0.0.2

I run my own DNS servers, and I'd like to continue using those for the wireguard peers. Hosts on my network are static. DHCP service is handled by the primary DNS server.

I've tried various firewall rules and NAT rules and nothing seems to work. Do you guys have any ideas what I'm missing?

Thanks

Hi, jollyrogr,

the wireguard peer allowed address must include the network that you want the access to also.

Example: allowed-address=10.0.0.2/32, 192.168.88.0/24

On top of any necessary firewall permission.

Thanks for the suggestion. Doesn't appear that that was the issue though. I got it working - turns out I had entered the wrong UDP port in the wireguard app on my phone. :man_facepalming: Step 1 is check the obvious, right?

After that was corrected, and enabled the input chain firewall rule, I had LAN connectivity but no DNS.

To fix that, I modified the two forward chain rules which force all LAN users to use my DNS servers by adding "in-interface=!wg1". Might be a better way to do that, but it worked.

Current rules:
