What are some of the things you do when you install pfSense?
-
The most important… Install a better shell (bash ;D) if you are familiar with it and use a shell in pfSense a lot.
Disable State killing in Advanced / Gateway Monitoring section for non-multi-wan setups. This always gets me when I forget and later find connections being killed when the external wan link just temporarily goes down for a very short amount of time.
-
I also tend to add 3+ NTP servers so there are at least four listed. It helps to keep the clock accurate over time.
And change the gateway monitor IPs to something farther out, such as the DNS servers. -

Thanks for the input.
For some reason shell keeps disconnecting on me after few minutes. Is there some timer on it? Also, can you please explain how to install a better shell? -

Also, what is the gateway monitor IPs?0.pfsense.pool.ntp.org through 3.pfsense.pool.ntp.org - using the numbers makes sure you get a different "sub" pool that won't have overlapping servers.

0.pfsense.pool.ntp.org through 3.pfsense.pool.ntp.org - using the numbers makes sure you get a different "sub" pool that won't have overlapping servers.
This makes for a great update in future versions. Why not just add this as default.
Also, some things I would do that is not mentioned:
-install cron package
-set nanobsd RRD graphs to 12 hours so RRD graphs are not all lost if system is unexpectedly turned off
-disable HTTP Referrer to WAN access from outside doesn't become an issue
-assign a universal password for console port - this may not be so secure but at least there is some security and some less headache when a universal password is used. -
Disable State killing in Advanced / Gateway Monitoring section for non-multi-wan setups.
That's System -> Advanced click on Miscellaneous tab and scroll down to Gateway Monitoring section.

Set up DNS on the box and set up NTP on the box.
Also Openvpn.Use my public IP as DNS server, NTP server and Openvpn Server when traveling in some parts of the world.
(Your personal public IP is so obscure as to not be on any list of things to block overseas)Exposing the DNS forwarder to the public is a very, very bad idea. It doesn't matter how obscure you believe your IP is, it will be found by automated scanners and used for DNS amplification DoS attacks if a "bad" scanner finds it. If a "good" scanner finds it, you could find yourself on a blacklist.

Open to the public NTP servers aren't hard to find. You really should select public stratum-2 servers and avoid stratum-1 servers unless your ISP offers one. Look for a close (in net hops / delay) open server that does not require you to request permission to connect for the least hassle.
NTP site: http://support.ntp.org/bin/view/Servers/
Rules: http://support.ntp.org/bin/view/Servers/RulesOfEngagement
Stratum 2 list: http://support.ntp.org/bin/view/Servers/StratumTwoTimeServers
If you don't have several open stratum-2 servers near you then using a pool isn't a bad option.
NTP Pool List: http://www.pool.ntp.org/en/
Keep an eye on your status page (pfsense/status_ntpd.php) and tune your list of servers by dropping ones not providing you usable responses.
I use my ISP's (Cox Cable) stratum-1 NTP server since it is close to me (in net hops) and is very reliable and one of the Phoenix, Arizona public library servers. I also use a local NTP server on my LAN for when my net connection is down. I have tried one of these http://www.pool.ntp.org/zone/north-america pools from time to time but it usually shows up on the status list as an outlier so I drop it after a couple days.

Set System > Firmware > Update Settings to either Stable or Developmental firmware. I would set it to developmental having learned my lesson of seeing broken features in stable versions but working in developmental version - many vouch for dev version to be stable in production.
