Setup 1 LAN/OPT connection to always be accessible ?

[kilko]

Hi,

I've been trying to configure pfSense for a few days… fidling about it..
I've already ordered the book from amazon, looking forward to reading.

Q: How can I setup 1 OPT or LAN connection to ALWAYS be accessible.

Reason;
I always seem to configure.. and then lock my self out (doh!)... and I would like to setup one lan connection- that I can plug into, with static IP - and connect to reconfigure the pfsense system again.

This would really help me to always have access and to test firewall settings etc..
