I have several small business clients using either Linksys BEFSX41 or BEFVP41 routers to connect SOHO's to their main offices.
Where I have cable modem on both ends, the tunnels setup and stay up with no issues. When I bring DSL into the mix, I can either have the VPN tunnel up OR I can browse the web, but not both.
I have this issue at multiple sites. The common items are:
Westell 6100 series modem
Linksys BEFSX41 router
I have tried all kinds of firmware upgrades/downgrades on the Linksys to no avail. Has anyone incurred these same issues? How did you fix it?
