Hi,,, we have 5 sites using BCM50a, with VPN tunneling, we are having issues where the tunnels /internet drop and do not re-establish,,, are there any known issues with the older ADSL cards using ADSL2 technology...does anybody know if the ADSL router cards in release's 5 & 6 are rejigged to work with ADSL2, maybe our router cards are too old ?? any thought would be great
