The Linksys responds to a port probe by replying with an “open” or “closed” status. General VPN help can be found on this page, including a link to a very complete Checkpoint Firewall-1 FAQ page. Turned it on, VPN circuit came up and runs fine.Ĩ/2/00 Still having problems getting IPsec to work? Check this. Since the router does NAT, it seemed like the thing to try. It was labled “Use NAT Transparency Mode”. Lucky me, there was exactly such a switch. I actually started up a tech support call with Linksys when I decided to check the VPN client code to see if there was some sort of configuration switch that was obvious. I was able to watch packets go out through the router to the VPN server at our site, but no packets made it back through the router. You can download at the IntraPort Client Reference Guide here (in PDF format), or find out more about the IntraPort product line here.ĥ/22/00 Try this if you’re having problems getting the IntraPort VPN working:Īt first I couldn’t get VPN to work. NOTE: The IntraPort client must be used with an IntraPort server. The symptom is that RavlinSoft fails to establish a SA it looks like it does not receive the Radius response after the UserID and Password are entered.Ĭompatible Systems(now a part of Cisco) IntraPort VPN client, which is IPSec based, will work, even without IPsec forwarding turned on. NOTE: We’ve also received a negative report for Redcreek RavlinSoft 3.40 NT and firmware versions 1.30 and 1.33 BETA. Netscreen-5e VPN/Firewall appliance (Thnx Mike Johnson!) We’ve received successful reports of the following IPSec clients working with the new firmware:Ĭheckpoint VPN-1 (see this link if you have problems) NOTE: If you are using V1.30.5 or higher firmware, make sure you enable IPsec pass-through on the Filters Admin page. ![]() You can find more general PPTP information on this page, and general VPN help on this page. NOTE: No matter which version firmware you use, you will need to set the PPTP server computer as the DMZ computer and remove any Port 1723 forwarding. This problem was fixed as of the V1.23 firmware update, so just upgrade to the latest firmware if your firmware revision is lower than 1.23. Many users have reported problems accessing a PPTP server on the LAN side of the router from the Internet. (This is a common limitation for inexpensive NAT routers.) NOTE: Although multiple PPTP clients can be passed thru, only one PPTP client can connect per PPTP server. You also need to properly configure a VPN connection profile in each of your PPTP clients. If you have PPTP Clients on your LAN, you just need to enable PPTP pass-thru as noted above. PPTP is Microsoft’s protocol for Virtual Private Networks (VPN). NOTE: If you are using V1.30.5 or higher firmware, make sure you enable PPTP pass-through on the Filters Admin page. You now should be able to connect to the Internet and the router will take care of managing the PPPoE login.

Go here for more info.Īlso see the PPPoE help information on this page. There’s also a Windows application you can try. If you are having problems maintaining a PPPoE connection, try V1.35 or higher firmware. You then may need to forward ports to your VPN client, based on the type of VPN connection you are using. Upgrading to version 1.39 or higher firmware will fix the packet size problem. In some firmware versions there is a problem with the router’s ability to properly adjust the packet size for a connection that uses BOTH PPPoE and one of the VPN protocols. If you are trying to use either PPTP or IPsec tunnels over a PPPoE connection, you may have problems establishing a connection. Updated 9/3/01 Problems using PPPoE AND VPN ![]() Upgrade instructions are in a ReadME doc that comes with the update.
