DHCP reservation - GW
-
Hmm, this feature requests appears to be in place already: https://redmine.pfsense.org/issues/11927 but the suggested workaround there, using the dhcp option 3 directly, can be applied to a static mapping.
And in fact it looks like this exact use case has been proven:

@stephenw10 thats funny actually I didn't recall that thread at all ;) But this is really just a rehash of that thread ;) and I had suggested doing what you had said about pool to none, and set reservations for those that want a gateway..

Tried it out on an old iPad. Still getting a GW, but it may need a more aggressive approach to get past Apple being helpful.
I like the approach and will try the same trick to not give DNS servers to the cameras.Thank you for searching better than I did...

Maybe the value type there should be IP address.
-
@andyrh ok just tried this on my windows pc.
So I set it to dhcp, got a lease with gateway per dhcp scope, etc
Then set up a reservation for 192.168.9.66, and set option 3 with nothing.. and released and renewed and got the .66 address, but no gateway..
-
Ah, nice!
-
@stephenw10 yeah that seems to be a good option for sure when you don't want a client to have a gateway. I think that should work for @AndyRH

Something went wrong around 13:50 and DHCP became corrupted. Had to restore it. (remember kids, backups are for fun, restores are serious)
I have a new weekend project...
Lots of 89884 messages then a crash. A restart did not work so I went to the backup.

Hmm, just by adding the option value to a static mapping?
-
@stephenw10 That is my guess. I will test it this weekend.
-
I finally got back to this. I was not able to reproduce the problem. It is now working as expected.
-
Just in case someone wonders by...
If the DHCP scope has a GW value of "none", if you do not specify a GW in a static mapping the host will not get a GW. -
Ah, yes that would do it. The static values override whatever is in the main config. So leaving it empty there would not override 'none' set in the main config.
