|Summary||0002253: Firewall not passing GRE packets|
|Description||I have two rules set up - one to pass tcp 1723 and another to pass Protocol 47 GRE to a single server running RRAS. Endian is not allowing GRE packets through to the server. I have confirmed this with the MS utilities pptpsrv and pptpclnt. The test makes a connection over 1723 but cannot get any packets to pass with GRE.|
ANY suggestions would be greatly appreciated. I don't want to re-do the fireall with IPcop or Smoothwall at this point but we need PPTP VPN availability.
Am I missing something?
|Tags||No tags attached.|
|is t his a port forward or are you connecting from green to a pptp server in red?|
|Sorry - this is a port forward from red to green.|
I also can confirm this problem on two seperate EFW2.2 firewalls.
I have the same two rules setup on EFW 2.2. To port forward from internet (red) to lan (green) for a pptp server on green, TCP 1723 and GRE and am unable to authenticate/connect due to GRE packets not passing to server via EFW firewall.
|can anyone confirm this issue also for 2.3?|
I can. After my 2.2 experience I went to 2.3 which did work for a while (a day) but has since stopped.
Interestingly, I use 2.2 on my personal home network and the VPN works fine so I'm not sure what the deal is here. I'm going to mount an ISA server as a test to make sure it's not provider related.
|modem/router related is more likely than provider related IMHO|
How are configured the two uplinks? In bridge mode?
Are the two modems/routers identical?
The uplinks are default - I haven't changed anything there since install. How do I check what mode they are in?
The two modems/routers are not identical but I know that both ISP services are wide open to each firewall.
|I thought I had it figured out by adding the GRE rule to the "System Access" section in Firewall. It worked for about 12 hours and then stopped working.|
