We've had this. Took to their customer forum to start with which got me nowhere. Then took to Twitter and referenced the forum. Eventually solved.
More recently if you just straight to their forum and post the serial and a traceroute they pick it up really quickly and "resync" your unit. Had to do a couple end of last month. Back on within a couple of hours. Forum.vodafone.co.uk is the place to go.

We have just taken over the internet supply of a site (so changed customers IP addresses) and several users have Vodafone Suresignals which no longer work after the switch. We have not changed their routers just their IP addresses. Vodafone 1st line support just keeps telling the customers that the ISP is blocking their IPsec tunnels which we are not. It looks to me like Vodafone might have some whitelists for these devices but I am speculating! Thanks Best regards, Paul
