SuSE 9.1 VPN Connection to WatchGuard Firebox 4500

System Specifications:
SuSE 9.1 Professional

Using pptpconfig I have set up a VPN connection using these details:

Name: VPN
Domain: none
Username: username
Password: password

Routing Style: Client to LAN
Networks: CompanyNetwork

Automatic: unchecked
Servers: blank
Options: blank

Require Microsoft Point to Point Encryption (MPPE): Unchecked
Refuse 40 bit Encryption: Unchecked
Refuse 128 bit Encryption: Unchecked
Refuse Stateless Encryption: Unchecked
Refuse to Authenticate with EAP: Checked

Start tunnel when this program starts: Unchecked
Reconnect if disconnected: Checked
Enabled connection debugging facilities: Checked
Options (pppd): blank
Options (pptp): blank

Selecting my created tunnel and hitting start brings up a new X window with the connection status in it.

My information, slightly edited, is below:

The VPN server is a WatchGuard 4500. I connect to it routinely from Windows XP Professional (both without SP1 and with SP1). The general settings under Windows XP are:

Host Name or IP Address: XXX.XXX.XXX.XXX

Display progress while connecting: Checked
Prompt for name and password, certificate, etc: Checked
Include Windows logon domain: Unchecked
Redial Attempts: 3
Time between Redial Attempts: 1 minute
Idle Time before hanging up: Never
Redial Line if Dropped: Checked

Typical: Checked
Validate my identity as follows: Require secured password
Automatically use my Windows logon name and password (and domain, if any): Unchecked
Require data encryption (disconnect if none): Checked

Type of VPN: Automatic
Enable LCP Extensions: Checked
Enable software compression: Checked
Negotiate multi link for single link connections: Unchecked

Internet (TCP/IP) Protocol Settings
Obtain an IP address automatically: Selected
Obtain DNS server address automatically: Selected
Use default gateway on remote network: Unchecked
DNS server addresses: blank
WINS server addresses: blank

I am not an IPSec user, I am a PPTP user.

The end result is that I can't get any traffic to go over the created device. The data just goes poof. No pings, traceroutes, nada. This is brand new install of SuSE 9.1 as well.

Any help?

need help

I am sorry. I am not that familiar with the problem. But, I may need some help from you. You were talking about VPN from SuSE 9.1 to Firebox. We have a similar setup with SuSE 9.0 and Firebox 500. Can you please tell me how to set up an VPN connection from SuSE 9.0 Firewall to the Firebox it will be very helpful.

Same problem with SuSE 10.0. . .

It seems to have been quite a while since bmschkerke posted his original question, but I am having this EXACT same problem with SuSE 10.0, as well.

If anyone has any further ideas, your input would be greatly appreciated.
