Cisco RV340 - dropping syn/ack from website

CrazyEggHead

Hello All,

I currently have a 1GB symmetric internet connection through my ISP which uses a PPPoE login for its connection. I am using a Cisco RV340 as my router / PPPoE dialer and am running 1.0.03.20 firmware.  I have a problem when I go to web URL https://admin.mailroute.net (IP 199.89.0.117).  The main website https://mailroute.net works fine, but as soon as you click login you get redirected to the above.  Topology is very basic:

ISP > Cisco RV340 > Client

The setup on the router is fairly basic right now, just have the PPPoE setup on the WAN, and not much else.

I have tried:

-Dropping MTU to 1400 (just in case it was MTU issue with PPPoE overhead)

-create static access rule to permit all (default canned is also set to permit all traffic)

-If I switch to a different vendor router with PPPoE this URL works fine.

-Downgraded to a firmware about 2 years old and tried the latest firmware within the past few months was released, same issue.

-Factory reset cisco router and performed basic setup again, same issue.

 

I'm at a loss, any input appreciated.
