Hello All, I am using the R2S with FriendlyWRT as home VPN routers. I have about a dozen of them in the field now in different employee's home offices. Twice now I've come across an issue where the WAN link light just blinks when it's connected to the employee's home internet providers equipment. I've use different patch cables. The LAN port links up just fine, but the WAN port won't. Does anyone have any ideas?
