Sonicwall Vpn Client Linux

The Sonicwall GVC is not compatible with Linux (it's a Windows application), so you cannot use that program. Adonis community edition for mac. However, Sonicwall published a document regarding how to use a Linux machine to VPN into sonicwall.

Hi,I'm not a networking guy.I'm trying to connect to my Employer's VPN using my CentOS box running Gnome.I used the GUI Network configuration panel.I entered in the Gateway IP address (verified with a ping that it is reachable)I entered my usernameI left the user password blankI entered the pre-shared key (and verified it numerous times)Under advanced, for both Phase 1 and Phase 2, I entered:aes256-sha1;modp1024Nothing works. It tries for a while to connect and then seems to time out.Now I am sort of out of ideas. Here is the output of a bunch of different commands that I have collected from the internet, but they are all a bit out of my level of understanding.Here are the contents of my /etc/NetworkManager/system-connections/Employer file (Employer is what I named my VPN profile). Code: connectionid=Employeruuid=type=vpnautoconnect=falsepermissions=user:me:;vpnesp=aes256-sha1;modp1024ike=aes256-sha1;modp1024leftxauthusername=mepskinputmodes=savepskvalue-flags=0right=NN.NN.NN.Nxauthpassword-flags=2xauthpasswordinputmodes=askservice-type=org.freedesktop.NetworkManager.libreswanvpn-secretspskvalue=ipv4dns-search=method=autoipv6addr-gen-mode=stable-privacydns-search=method=autoHere are some lines from my /var/log/messages file: (I redacted some things that I don't understand and probably don't need redacting. But I'm trying to be careful). Code: ike-scan NN.NN.NN.NStarting ike-scan 1.9 with 1 hosts (Mode Handshake returned HDR=(CKY-R=) SA=(Enc=3DES Hash=SHA1 Group=2:modp1024 Auth=PSK LifeType=Seconds LifeDuration=28800) VID=Ending ike-scan 1.9: 1 hosts scanned in 0.037 seconds (26.81 hosts/sec). 1 returned handshake; 0 returned notifyAnd here are the settings that I got from our IT guy (he basically just set up the SonicWall in its default state and doesn't fully understand it, so he isn't really able to help me out).
