Hey guys,
I installed tinc on a linux server which connects to the internet.
That server is linked via a wireless link with a Windows 2000
workstation. I installed tinc on the windows box too, and the vpn works
neat. The only problem is I don't know if the windows tap driver is able
to forward unknown IPs to a gateway. This is because if I try to ping
10.0.0.1 which is just another ethernet card in the router, I get a
"destination unreachable" error, because the tinc VPN subnet looks
like
10.0.2.0/24, where 10.0.2.1 is the router end, and 10.0.2.2 is the win2k
box. I can ping 10.0.2.1 from the win box.
The wireless link looks like this: 10.0.1.1 is the linux router,
10.0.1.2 is the win2k box.
In spite of the fact that the router works correctly, it even seems
that if I try to ping someone on internet from the windows box, I get
destination unreachable without the packets even getting tunneled
through the VPN by tinc, using the wireless link for transport. I tried
it with a sniffer, and indeed, packets dont even travel through the VPN
when I try to ping some internet IP. I conclusioned this is a limitation
of the windows tap driver.
If anyone knows better and can help me setup internet connection via
strong wireless vpn for this windows box, I will deeply appreciate it.
Best Regards,
Alin-Adrian Anton.

Those destination unreachable messages are generated by tinc, because it doesn't know a Subnet which matches the destination address of the packets you are trying to send. -- Met vriendelijke groet / with kind regards, Guus Sliepen <guus@sliepen.eu.org> -------------- next part -------------- A non-text attachment was scrubbed...

VPN is working, but I cannot ping internet sites. Is it possible to ping them through tinc? I tried subnet = 0.0.0.0, not working. Thank you so much for your time. Regards, Alin-Adrian Anton.

I need to compare some basic security properties for different VPN solutions. I have listed a few that I could think of below. If you have opinions about additional one, I will appreciate if you can list them here. Does Tinc Support the following (I have marked the ans's that I think I know): 1. Confidentiality: Yes (Packets are encrypted) 2. Data-integrity: Yes (using digest: SHA1) 3. Authentication/Non-Repudiation (Both at the session and data-packet level): Yes 4. Anti-Replay protection: ?? 5. Forward Secrecy: ?? 6. Does it have a user Space Impl: ??
