NAT compatible IPSec with UDP

Conventional NAT breaks VPN. Network address translation (NAT) allows you to hide your unregistered private IP addresses behind a set of registered IP addresses. This helps to protect your internal network from outside networks. NAT also helps to alleviate the IP address depletion problem, since many private addresses can be represented by a small set of registered addresses. Unfortunately, conventional NAT does not work on IPSec packets because when the packet goes through a NAT device, the source address in the packet changes, thereby invalidating the packet. When this happens, the receiving end of the VPN connection discards the packet and the VPN connection negotiations fail.

Firewalk

Firewalk is an active reconnaissance network security tool that attempts to determine what layer 4 protocols a given IP forwarding device will pass. Firewalk works by sending out TCP or UDP packets with a TTL one greater than the targeted gateway. If the gateway allows the traffic, it will forward the packets to the next hop where they will expire and elicit an ICMP_TIME_EXCEEDED message. If the gateway hostdoes not allow the traffic, it will likely drop the packets on the floor and we will see no response.Firewalk attempts to determine which protocols a router or firewall will block and which they will pass on to downstream hosts. It operates on an IP expiry technique, much like the commonly used Traceroute program. The IP expiry technique involves manipulating the time to live (TTL) field of the IP header to map out all intermediate routers or hops between a scanning host and the target host. In Firewalk, scans are then sent with a TTL value one hop higher than that of the target host. If the scan packets are blocked by an ACL or firewall, they are dropped or rejected. If allowed to pass through, they will expire and elicit an ICMP time exceeded message. Based upon the results of the scans, Firewalk can identify which ports are open.
