This question already has an answer here:

I need a static IP for a remote shutdown utility with my phone. What are the security implications of setting IP to static?

I feel the "attacker knows your IP won't change" argument may be a overrated threat. I use Norton 360 and VPN with Windows security center off (windows 7).

NB: The only port forward I have is a 5-digit UDP through the VPN.

  • I think the argument is better stated, "if an attacker finds a weakness, they can always return to your vulnerable port". That threat is up to you to accept or not. – schroeder Jun 8 '15 at 17:05
  • Would it be so hard to find the vulnerable host again after a IP change? (VPN is always on and shuffles IP use) – Manumit Jun 8 '15 at 17:08

    For instance, if a scanning bot is looking for weaknesses, finds your vulnerable port and enters you into a registry, then your record in that registry will continue to be valid. It might not matter in your situation, but the argument you state has more context to it. – schroeder Jun 8 '15 at 17:11
  • @schroeder what about posting that as an answer? – Steve Dodier-Lazaro Jun 10 '15 at 12:38
