I think IPv6 pass-through means there is a bridge between the WAN and the (single) LAN. If pass-through is needed for working IPv6 then I would say the ISP has done something wrong. With IPv6 the customer should get a routed prefix (/48, /52, /56, /60 or /64) for example using dhcpv6-pd, which doesn't require pass-through or bridging.

2019-5-13 · Implementing IPSEC. In this example, we will set up IPSEC to encrypt communications between two windows machines. The first machine, a windows 2012 server will act as the VPN server. The second machine, a Windows 10 client, will act as the VPN client. A LT2P IPSEC VPN can exchange either a pre-shared key or a certificate.

The benefit of disabling VPN passthrough is enhanced security by blocking open communication ports through the firewall that otherwise would be open and accessible. The drawback is that a user behind the gateway would not be able to establish a VPN connection, since the required VPN ports are blocked at the firewall. VPN Passthrough deals with the fact that encrypted IPsec (ESP) or PPTP (GRE) packets don't carry cleartext source and destination ports like unencrypted TCP/UDP packets do. Many-to-one outbound NAT translates both IP address and port number, letting many sessions share the same public IP address. VPN L2TP/IPSec passthrough with Cisco ASA 5505 6 posts mortem.

Posted: Fri Oct 26, 2007 8:12 am the VPN is not connecting..The site specifically says that the Pass Through must be enabled, port 1723 must be open and protocol GRE must be enabled. I oped port 1723 and set GRE. the only item I can't seem to find any info about is the VPN Pass Through even though they say the G1100 can do it in their manual.
