Hi folks,

Long time lurker, 1st time poster...
I was just wondering if there was any wise heads out there that might be able to answer a few questions for a curious mind...
I was wondering if there was any reason why my VF issue Echolife HG556a has the internet facing port 8081 open or could this simply be a case of mis-configuration on my part i.e. operator error?!

Things that I think maybe relevant to help anyone in answering this question:
-The router is running the lastest firmware from the VF site (V100R001C12B032SP01.bin)
-I have a VF Sure-signal (BSR FEMTO V1.2) {I'm thinking this maybe the most likely candidate here?}
-Naked Broadband Ultimate connection
-I have double checked port forwarding/mapping is not enabled

I stumbled on to this while running an Nmap scan on my home IP from work (yip I was pretty bored...) and this showed port 8081 as open.
Note - an internal scan from 192.168.1.x does NOT show this as open.

The results of the scan from an external ip were: (just partial results listed to show the difference between open/closed/filtered ports) 
PORT STATE SERVICE 
21/tcp filtered ftp 
22/tcp closed ssh 
23/tcp filtered telnet 
25/tcp closed smtp 
8081/tcp open blackice-icecap?
No other port was listed as open. 

I also double checked using the shieldsup! tool on the grc website and a couple of other web based scanners. 
So I was wondering if anyone could set my curious mind at rest.
Thanks in advance for your thoughts, my money is on the sure signal but now I just gotta know... ;-) 

*I've posted this on the vodafone forum also and will keep this post updated if I get a response. I hope this is posted on the right spot in this site.

Thanks again
Curious George
