DHCPd with multiple ipv4 subnets outside of local interface network. (300US$)

xbipin

the amount is fine but to my experience this would be tough to do as i had a similar requirement in the past but due to some restrictions it wasnt possible to do but lets see if some1 responds first, the amount can be worked on later

shade

I'm also interested for this for pfSense 2.1

I will chip in with $300

xbipin

$50 from me because as of now i dont require this but it would be a good feature to have and to support development

WetWilly

Alright, so that makes the current payout 850 US$.

xbipin, just for reference, could you try to locate the old thread? I tried to look through all your posts but it was too much of as hassle to scroll through 1172 posts.

Shame it's not possible to update the subject of original post to reflect the higher bounty.

xbipin

actually that thread was for something else but this question i had asked and i had got that reply, it would definitely be difficult to locate it but ill try searching from what i remember

shade

I can also increase my part of the bounty to 500US$.

That makes the current payout 1050 US$.

WetWilly

As 2.1 was released (Great work pfSense team) some variables in the bounty has changed for the easier.

Design it to be supported in 2.1 and in such a way that it can be deployed into upstream pfSense development (2.2).

The current bounty of 1050US$ is still valid.

marcelloc

I can take a look on it. :)

Basically you need a list of DCHP ranges on each interface tab?

It may depend on interface aliases and/or addresses?

Attached a first screenshot that "fix" gui to accept dhcp ranges for all configured networks on interface.

The service does not starts as it need fixes on code too.

All new functions may take some time as it will need a lot of changes.

Maybe a list of all configured subnets?

Very interesting Marcelloc! ;D

Before you spend any more time I just want to make sure we are on the same level with the specification on this bounty.
I would also like Shade to acknowledge before you start as he is funding the other half.

I will rewrite the specification, Shade please acknowledge that you still pledge to this bounty and that you are satisfied with the specification (maybe you have something to add?)

What we need is the following:

Possibility to configure multiple different subnets on the same interface under Services –> DHCP server.

This seems to be done on your first screenshot. However, I dont ever want a local IP interface inside the range of the additional subnets as this will not be a local network for pfsense. It is only going to be used for DHCP. E.g. pfsense will not be default gateway for those additional subnets. It might be nice to leave it as optional for other users though.

Each subnet shall be configurable with separate gateway, DNS, WINS, Domain name etc. (Same options as current dhcp-pool including static leases)
The DHCP leases shall be visible under Status –> DHCP Leases. Preferbly sorted with different frame per subnet, or any other way to easily separate the different subnets.
dhcpd logs for all subnets shall be visible under Status –> System logs --> DHCP.
It must be coded in such a way that the changes can be deployed to upstream pfSense development (2.2).

This is specifically a deal breaker for me, I don't want to be stuck with 2.1 forever in order to continue to use the functionality from this bounty. Marcello, it looks like you are very active on these forums. Would you say its possible to commit the code to upstream pfsense development once it's done?

Not needed
IPv6 support is not needed at this time.

If you need help with how to configure dhcpd.conf or if you have any other questons before getting started I can be of assistance.

WetWilly: It sound like we still need the same thing..

Marcelloc: Translated to config I need that the following works in the GUI

Local Lan Interface

option routers 172.16.0.5;
option subnet-mask 255.255.0.0;

deny unknown-clients;
}

I'm working based on these config result.

As soon as I get a working code, I'll post here for testing.

WetWilly

Shade, nice to hear.

Marcello. Looking forward to test your update!

marcelloc

I think I got it ;D

}

I'll send you modified files.

I've did minimum changes to current code to get easier to debugn and push to 2.2.

This code does not affect basic dhcp setup, gui or config

shimabuku

I would like to also chip in $100 :)

marcelloc

@shimabuku:

I would like to also chip in $100 :)

Great! ;D I'll send you this first version of the patch.

bennyc

This is something great & added value overall.
If really hope this makes it to the next releases (as accepted feature), and i'll also add in anther $50 to support dev a bit…

shade

@marcelloc:

I think I got it ;D

Great, I have downloaded the files and will test the update in the next couple of days…

eri--

You would probably have that development done from pfSense devs through support channel with the amount of 1600$.
For this feature it would not require more than that.

bennyc

I can hereby confirm the feature is working as requested in the bounty.
Tested the mod in following environment: x1250e running 2.1 & a couple of dhcp scopes configured outside of interface's subnet, c3560x doing L3 routing & ip-helper configured on some vlans pointing to pfsense.

all config (pfsense anyway) can be done in gui
dhcpd replies to correct (ip-helper) gateway, hands out IP in correct scope
dhcp leases are visible, sorted on IP ascending, in same page (room for improvement here, if more scopes are used the list can get long/crowded)
dhcp log page displays relevant information from all scopes (same here; leaves room for improvement)

example from dhcp log:
Sep 26 12:48:41 dhcpd: DHCPACK on 192.168.3.1 to 3x:cx:4x:cx:dx:8x (Win8Phone) via 192.168.3.254
Sep 26 12:48:41 dhcpd: DHCPREQUEST for 192.168.3.1 (192.168.1.254) from 3x:cx:4x:cx:dx:8x (Win8Phone) via 192.168.3.254

(yes my log is in reverse order ;D)

Great work Marcelloc!
