My V-Portal is sending out something to the internet approximately every 20 seconds when the phone is not in use. Is that something that is normal? I have my router in front of my V-Portal.
Every 20 seconds seems a bit excessive, but perhaps the V-Portal uses a different protocol than older ATAs. My VT2442 and RTP300 Vonage routers only do a TFTP (UDP port 69) and NTP (UDP port 123) sync about every 30 minutes when idle.
Since I assume you see this in your primary router's logs, perhaps you should examine those logs to see what kind of traffic is connecting. -- History does not long entrust the care of freedom to the weak or the timid. -- Dwight D.

reply to Bluefish That is the SIP registration and is perfectly normal. It serves two purposes:
1] let vonage know where on the internet your v-portal and phone number currently are residing
2] effectively opens a hole in any NAT routing or firewall device that might be on your network for the SIP traffic between vonage and the v-portal to pass through in the case of an incoming call notification. It repeats often in order to prevent the hole from timing out and closing.
hope that helps.

Thanks to you both. I was concerned that my V-Portal might have got hacked when it was in front of my router. (The allowable parameters for the V-Portal password are not very strong, that's why I ended up putting the V-Portal behind my router.)
