Hi,

I didn't succeed in resolving this issue on 8.04 release, but after I
migrated to 8.10 and kernel 2.6.27-7 it suddenly began to work... No
idea what was the problem, but now it works fine.

br, Nikolay

I get the same auth problem:

vpnc-connect: no response from target

I've tried recompiling vpnc with openssl but that doesn't solve it.

I have vpnc working on one machine but that one uses vpnc 0.4.0 (not upgraded from latest universe).

The difference in worklogs is the following:

Both machines are on the same LAN and run Intreprid with some small APT sources differences.

I looked at the code and first tried to disable DPD packets (using --dpd-idle 0) as this was the only difference in the logged communication exchange, but this didn't help.

I finally added

NAT Traversal Mode cisco-udp

to my vpnc conf file and vpnc works again. http://www.gossamer-threads.com/lists/vpnc/devel/1874?search_string=no%20response%20from%20target;#1874

Thank you Jerome, that workaround fixes the bug for me with 0.5.3r449-2 of vpnc installed.

Ditto, same problem here. However, I observed that if my gateway is 192.168.1.1, I can connect to VPN. But if I change my wlan0, and connect via different gateway 192.168.1.2, I will get the NO RESPONSE message. My --debug 3 log is similar to that given in the bug description.

For now, configuring the NAT traversal to cisco-udp seems to fix the problem. I will get back here if the problem still persists.

sorry, hate to report that the issue still exists even if I set NAT Traversal to cisco-udp
any work-around/patch for this ? Its really hampering my work :(
I have to use a VBoxed CLI-Ubuntu , with exact same version of vpnc (but Ubuntu is 11.10 updated), on which the vpnc (autmagically) works!

I don't know how to fix this, there's just not enough information. Both Ubuntu versions 11.04 and 11.10 use exactly the same version of vpnc.

Please see if you can add extra information about the network itself; if it works in VirtualBox, the issues may be related to the network setup, the different gateway handling VPN traffic differently from the other.

Yup, same issue here. cisco-udp does not send traffic to port 10000 / udp on the far side.
