Did you install SE from 3rd party RPM package or compiled SE yourself?

I did follow the instruction here

post the result of "uname -a" please

[root@main ~]# uname -a
Linux main 2.6.18-371.6.1.el5 #1 SMP Wed Mar 12 20:08:05 EDT 2014 i686 i686 i386 GNU/Linux
You have new mail in /var/spool/mail/root
[root@main ~]#

Your OS is 32 bit... that manual is for 64 bit systems.

Take care.

I did install the 32 bit tar file and I did follow the instruction will it make difference ?

show the name of the file you downloaded.

softether-vpnclient-v4.06-9435-beta-2014.03.26-linux-x86-32bit.tar.g z
how can I delete all the files related to and re-compile it one more time is it enough to just delete all folder?

Thanks,

yes and report back.

It works my typo or mistake on ver.

Do you have any Idea how to push the VPN to only use ICMP tunnel ?

I know how to establish a VPN connection using ICMP, but I have no any idea "how to push the VPN to only use ICMP tunnel".

Cheers!

maybe disabling Nat Traversal, enable VPN over ICMP, and client side connects to a port that ain't listening in server side. Client will try to establish for TCP, UDP, ICMP and DNS. Using random TCP port that's not listening will eventually fail, Random UDP port will also fail as Nat Traversal is disabled, Vpn over DNS should be disable so it will also fail and so the only connection left would be ICMP. But this is just a theory base on my understanding with the source. :P I haven't tried it.

Thanks, Do you have any Idea how can I edit client config file via vim editor in linux?
what is the config file name in linux?

Thanks

you can edit the files called vpn_server.config in /usr/local/vpnserver or /usr/vpnserver where you install it. I never use vim though as im use to nano. After modifying the config just restart the vpnserver service and you are good to go. I just tested it and turns out that my theory works.

I also tested VPN over DNS but the thing is it doesn't retrieve the ip as it should. Maybe it go something to do with my settings.

Thanks do you have any Idea how to add PUBLIC IP address and assign it to the vpn client?
I need to give static public IP address which I have couple routed to the server to the specific user on VPN server or to the virtual hub to give this opportunity to the user to use valid static IP instead of NAT or DHCP IP.

Thanks

To make vpn over dns work, you need to connect through a dns serivice or use your server hostname, not the public IP address, I have a similar set up that works for me, I am able to connect to the internet for free through an ISP portal, the only problem is that sometimes it doesn't connect straight way until I connect to a direct internet connection and then disconnect and connect to my ISP portal internet again.

You need to set an A record on a domain you already own pointing to your server Public IP. then connect with that sub-domain.
