Can a USG50 misconfigured cause massive packet loss?
I have COX Residential Premier internet with phone and I feel like the problem is related to Cox equipment/infrastructure but I can't be positive.
I have a USG 50 which worked fine for a few weeks after installing it. Previous to that I had a Buffalo WZR-HP-G300NH which is now used as an access point only.
The problems started cropping up mid-may not long after I established a site to site vpn connection to my office. Now I have severe packetloss. Could I have misconfigured something that could cause this to happen? The only changes I've made are establishing a site to site vpn connection where I'm on the 10.10.12.x range (1 physical port assigned to this range) and the remote office is 192.168.x.x. Nothing fancy and it's up 24 hours/day. I have a couple firewall rules setup to allow a connection from hamachi/logmein (only enabled infrequently and not during the issue). I have two other ip addresses blocked for suspicious activity but that's it. Everything else is default.
I'm just exploring this avenue in case it could somehow cause my cable modem to freak out. I do have telephone service as well and that will fail but it's connected directly to the cable modem so if there is a problem with the router it would have to cause the cable modem to die taking out the phone too - seems unlikely.
Anybody know if there are issues with a Cisco DPQ3212 and a ZyXEL USG 50? I've already had a couple Cox techs out for this issue and they've replaced the modem, line from pole to house and the cable from the box to my modem. From here it's either me or something else further out in Cox's infrastructure but they say nobody has reported a problem.
