if vermin is a cable company there might be a fault in the area, this happen to my friend on vm, it was working fine for like a year then one day stopped working. it was off for like 3 weeks, the line was from me so i new all was fine, but every time i restarted my server his box came on, but only for a while, sometimes it worked for 3 mins and other times 20mins, if u can restart server see if that helps, but fone cable and ask is there a fault or are the doing upgrades, you can tell them your ip camera on wat ever the port is, and it isnt working and u want to no why, tell them you use a dyndns to view camers and they wont work, they will fix problem or tell u what is wrong, i hope this helps..
