As a quick hack, is there a way to set up something to listen on another port (say, 8001) so that from the local network I could connect 192.168.1.x:8001 and it would tunnel the traffic between the client and 127.0.0.1:8000?
Aug 03, 2006 Understanding VPN IPSec Tunnel Mode and IPSec Transport Understanding IPSec Modes –Tunnel Mode & Transport Mode. IPSec can be configured to operate in two different modes, Tunnel and Transport mode. Use of each mode depends on the requirements and implementation of IPSec. IPSec Tunnel Mode. IPSec tunnel mode is the default mode. With tunnel mode, the entire original IP packet is protected by IPSec. What is an IP tunnel? - Quora

The authentication used is very simple, and works as follows. The user first specifies a password or passphrase, which is then hashed using the MD5 algorithm (Ping Tunnel uses the implementation by L. Peter Deutsch, available here. Note that the implementation is included with Ping Tunnel, so there is no need to download it separately). May 17, 2019 · IPIP tunnel, just as the name suggests, is an IP over IP tunnel, defined in RFC 2003. The IPIP tunnel header looks like: It’s typically used to connect two internal IPv4 subnets through public IPv4 internet. It has the lowest overhead but can only transmit IPv4 unicast traffic. That means you cannot send multicast via IPIP tunnel. Configure IP Tunnels. Configuring IP tunnels on a Citrix ADC appliance consists of creating IP tunnel entities. An IP tunnel entity specifies the local and remote tunnel end-point IP addresses and the protocol to be used for the IP tunnel. Note: While configuring an IP tunnel in a cluster setup, the local IP address must be a striped SNIP address.
