Client VPN not connecting

I am having an issue with connecting to a client VPN. 

 

the machine is win 10 but i also tried to connect from a chromebook. Both can connect to other client vpns i have set up just fine

 

the client vpn is on a connection to comcast. not using comcasts hardware but a motorola SB6183.

meraki connects directly to motorola modem

 

as far as i can tell no VPN connection logs in the meraki. the VPN connection just times out

 

any ideas what to look for?

 

thanks

 

Mike

Is comcast running nat?

If so, do the forward the vpn to to the meraki mx ip?

no NAT involved. motorola cable modem (no router) directly connected to cable internet. MX connected directly to cable modem

I don't know if it's applicable to Comcast, but check your ISP doesn't do Carrier Grade NAT (CG-NAT). That will prevent you from initiating inbound connections.

 

If you're manual port forwarding for your site-to-site, double check there's no port overlaps.
