I need to monitor our connection over a VPN tunnel between 2 firewalls across the Internet and be able to see if the problem is on the ISP carrier side, any recommendations for network device. I have 2 sonicwall firewalls that connect the 2 offices via VPN tunnel, but the remote office has been having slow connections and freezing up after installing a new Fibre internet connection with Embarq. When I call them to tell them the circuit is acting flaky, they tell me everything is fine on there equipment it must be on ours. The only way to prove it is to bypass my firewall and if I do that I disconnect our remote office completely. Would placing a layer 3 switch in between our firewall and their router allow me to plug a laptop in and run testing, bypassing our firewalls? Anyone out there that might have a suggestion for me to check on our LANs or firewalls to see if the problem really is on our side.
Thanks, frustrated in Florida
