Access router from WAN

I thought this should be fairly simple, I have this rule here

and that this is the ONLY rule I have in my firewall

When I first add this rule, I was able to web into the router. But after reboot, I can't anymore... any reason why that would be?? Very weird....

Do not do this -- it is a recipe for disaster with respect to security.

Use a VPN instead.

Also, this only works if you have a public IP address.
