i need help. i need to know what Hardware revision is running on linksys model BEFSR41 ver.3.1 and BEFSR41 ver.4 i know that those box can come with ether linux or VxWorks. the problem is that i have a nortel vpn client initiating a vpn connection to a remote gate trought the linksys. this part does work but looks like the linksys drop the packet on its way back. that of course is only with BEFSR41 ver.3.1 . The firmware version is 1.05.03. but if we use the BEFSR41 ver.4 ... it works.... so i am almost 100% sure that one is running linux and the other one runs Vxworks but linksys will not tell me this info. we can confirm this by knowing that we cannot put version 3 on a version 4 device and vise versa. anyone can help.
