I want to Manage Linksys RV082 through the WAN connection, My Firewall Configuration is :
Firewall : Enable
DoS : Enable
Block WAN Request isable
Remote Management :Enable Port: 80
HTTPS : Enable Multicast Pass Through : Disable
well, your settings look right. Have you tried it? You should be able to access it though your public IP address.
Make sure you have a really good password on that, and keep your BIOS updated.
I have tried it, if firewall is enabled, I can't access trough wan, example : http://18.104.22.168:8080, if firewall is disabled, I can access, but my access rules is also disabled. I have good password (12 character), I have update new firmware.
