I have two Juniper SSG 5 routers connected through a VPN tunnel. About every 6 hours for one and 12 hours for the other, the outgoing traffic will be slowed and then stopped. I can still remote into systems behind them and even connect through a PPTP connection. However, any system on those routers cannot connect to the internet. The only way I have found thus far to get them back up is to reset the routers about every 6 hours. Anyone know why they are doing this?
