Can't get DMZ to work, need open ports for live streaming a radio show
I've been on the phone all day the last two days to no avail. I need ports 80 and 443 open to connect to a radio network website. I've tried Port Forwarding those two ports, but they remain closed. Now, i've set up DMZ which is supposed to open ALL ports but NOTHING happens. I still can't get 80 or 443 open, not to mention dozens more that DMZ isn't affecting either.
Could it be a bad modem? My service works great in every other way. I feel like I need someone to dial into my PC and network but I've talked to 4 techs (including two "advanced" techs) and they keep trying to have me do things I've already done on My Xfi. DMZ should open EVERYTHING up.
Has anyone had a similar experience or is there something else I can try? I'd hate to switch to CenturyLink but if this can't be resolved I'll have to.
