TTL value

[Joulius]

I have a problem with my ISP. The TTL received from gateway is 1, so when I try to create an Internet Connection Sharing for another computer, the TTL value is decreased, becoming 0, so all packets will be droped for that second computer.
I was wondering is there is a setting or a registry key or a program that will prevent decreasing of the TTL value when routing.
Thank you!

I've never done this... why would you want to do this? Your other machine should be 1 hop away as well. Is it not getting an IP?

Here is link that talks about registry settings:

All packets received from gateway have TTL = 1. By routing them to my second computer, the TTL is automatically decreased. What I'm looking for is something to prevent this.
Some friends of mine said that this can be easily done under Linux with iptables, but no one knows how/if it can be done under Windows.
