SSL timeout - Guest Network over PPPOE

[Jack Yaz]

Hi,

Strange issue! I have my guest network on a separate subnet using my YazFi script. Clients can connect to the router, ping tracert and nslookup on WAN but browser's report connection timed out.

If i route them over a VPN client on the router there are no problems so I'm assuming something is wrong with the WAN. I didn't have this issue on cable Internet only now I have to use ppoe..

Any ideas? I will attempt a factory reset if needed but to me it seems I'm missing something obvious.

Particularly curious that all connectivity except browsing works!

On further inspection its requests to SSL content that time out. Does this help?

MTU issue and placement of rule in forward chain. Needs to come after

-A FORWARD -p tcp -m tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu
