I have a tunnel established between a pair of BEFSX41s (version 2, latest firmware (1.59.2?)). Some communications through the tunnel works, and some doesn't and I don't see any pattern. I'm using different subnets for the internal addresses of the two LANs.
I can use VNC to connect to one of the remote computers using its LAN address. That's good.
I can ping some, but not all, of the computers on the remote side. That's bad. I can ping several Windows workstations (WinXP), but not a Linux server. I know it responds to pings, because I tested it from a computer on the remote side when I was connected with VNC. I'm not sure that Windows vs. Linux has anything to do with it.
I can't make any Windows connections, such as connecting to a shared folder. That's bad. I can't browse for any computers by name, and I can't see them even if I use their IP address (e.g. \\\\192.168.123.100). I have the "Broadcast NetBIOS" flag checked on both routers, but regardless I would think specifying the IP address would work.
This firmware is only about a month old, and seems MUCH better than previous versions in all respects. I'm hesitant to blame it for any VPN problems -- there are lots of other reasons why VPN can fail.
Does anybody else have experience with a similar setup?
