Does changing WAN IP affect running tasks?

Hi,

Hopefully a few questions that some of you with greater tech know-how can answer for me. Image may be NSFW.

I use a VPN which disconnects sometimes and can give me a different IP when it reconnects.

In BitComet Statistics info window, BitComet displays the external IP I had when the client started even if it changes while BitComet is running.

Will this change have any effect on existing peers if they try to reconnect?

When BitComet set up connections to new peers, will the difference in WAN IP be an issue?

Is there any way to configure BitComet to check the ports at regular intervals (same as right-clicking bottom right and choosing 'Check again') or should I try requesting it in the Suggestions forum?

Or does BitComet reconfigure everything when it senses a new WAN IP and just not update the Statistics page and I can just pop this to the Bug forum Image may be NSFW.

Thanks
