Thank you so much for making this helpful setup document. I have been able to connect to my work VPN using your tutorial on Windows Shrew VPN. When I tried it on Linux (with ike version 2.1.7 on Ubuntu 11), however, it failed to connect.
On linux, the message I got from the GUI when trying to connect is:
gateway not responding
detached from key daemon ...
Do you know why it would fail?
One thing I noticed is that the options for "Phase 2 -> Transform Algorithm" do not include "esp-3des" (or anything with "esp" in the name). Instead I chose "3des". Do you think this is the issue? Is there a way to make this work on Linux?
"esp-3des" is only an option in the Shrew VPN Client. This option is called 3DES in our router. However, this should not be the reason why it is failing to establish the tunnel. Can you please make sure that you are not using any firewall rules that might prevent the connection (i.e. iptables).
You can check it using the following commands when you are logged in as a superuser (root):
# iptables -L
# iptables -L -t nat
Reset them using:
# iptables -F
# iptables -X
Please report if you have found out what might be the reason. I will try to create a tunnel using Linux environment early next year.
I tried resetting the iptables with the commands you mentioned, and I still have the problem. I don't understand the output of the iptables command, but I can post the output before and after resetting, if you want to see it.
