Will changing router IP change all ips in firewall rules?
-
I have a situation where I am looking at changing the router subnet from 192.168.1.1 to 192.168.100.1, and I have allot of rules in the firewall.
If I change the pfsense IP is there an easy way for all the ips in the rule section to be changed to the new 192.168.100.X automatically?

That depends on how you wrote your rules.
If your LAN is 10.0.0.0/24 and you use in the default rule on the LAN as "source": "subnet: 10.0.0.0/24"
Then yes you will need to rewrite all your rules.However if you use as "source": "subnet: lan-subnet" then you wont have to change the rule.

I'm new to this so bear with me :D
An example of a rule from the pfsense box right now is something like this:
Proto Source Port Destination Port Gateway Schedule
TCP * * 192.168.1.15 13500 *In NAT its:
If Proto Ext. port range NAT IP Int. port range Description
WAN TCP 13500 192.168.1.25 (ext.: 67.69.12.98) 13500
our LAN is 192.168.1.1 / 24

Use aliases in your rules.
Like this you only have to change the alias.
