IPSEC LAN-to-LAN VPN Tunnel

I am trying to set up a LAN-to-LAN VPN tunnel behind my gateway. I am using a Sonicwall router behind the gateway and it keeps timing out on both ends for IKE setup. Does Comcast block UDP 500 and IPSEC/ESP Protocol 50? Also it appears that I am unable to get to the management interface of the Sonicwall despite setting up a firewall rule to allow this from certain source IPs. Is inbound HTTP/HTTPS blocked? I have a static IP from Comcast.

Re: IPSEC LAN-to-LAN VPN Tunnel

Welcome, hhmi-philly.   Comcast does not block UDP 500 and IPSEC/ESP Protocol 50 on the network.  Applications running on devices behind the Comcast gateway is not accessible to Comcast.  HTTP/HTTPS inbound via the static IP are open and allowed based on rule set of the terminating device.  Here is a Link to some additional documentation for the Sonicwall.  

Thank You
