DHCPs assign wrong pools

jeroen234 · Jan 16, 2006, 7:22 PM

if its a bridge then jou have now 3 dhcp servers on 1 lan
that is how it coms that you get the whrong dhcp server
remove the bridge
en sub youre network up

lan ip 192.168.1.1/26
lan dhcp ip 192.168.1.1
dhcp range 192.168.1.2 - 192.168.1.63

lan2 ip 192.168.1.65/26
lan2 dhcp ip 192.168.1.65
dhcp range 192.168.1.66 - 192.168.1.127

Wireless ip 192.168.1.129/26
wireless dhcp ip 192.168.1.129
dhcp range 192.168.1.130 - 192.168.1.191

jeroen234, I know that you cant have 3 DHCPs for one bridge…. its not even possoble in the configuration... when u bridge interface it automatiaclly disables the DHCP for that interface (I hope, at least it hides the dhcp tab)

hoba · Jan 17, 2006, 7:18 PM

Sorry, I don'T understand the problem ::)

alexus · Jan 18, 2006, 3:34 AM

hoba, ok let me gust erace my brain and pretend im dummy user, lol
Just installes everything, got WAN and LAN interfaces running OK, and connectiong to the internet normally…
What I do to get other interface to use same DHCP pool as LAN, and that it will go to the internet? :-\

hoba · Jan 18, 2006, 7:14 AM

Basically if you bridge another interface to LAN the clients on this one should receive dhcp from the same server configured at LAN interface. Also check settings at system>advanced. If the filtering bridge is enabled there (this is an option of the newer versions of pfsense) you have to create pass rules at the bridged interface too. For the older versions you always needed the pass rules as the bridge was filtering by default but you should always be at the latest version.

alexus · Jan 18, 2006, 10:36 PM

aint working…
here is what i did
1. reset to defults
2. skipped VLANs setup
3. set the interfaces (LAN -> sis0, WAN -> sis1, opt1 - > sis2)
4. skiped wizard
5. in OPT1 selected bridge with LAN, and Enabled the interface
6. add firewall rule to pass anything from any and to any (all stars)
7. Pluged in to OPT1 released current ipaddress
8. renewed IP address on OPT1, got no DHCP reply....

(I also chekd bridge filtering and it is not cheked)
So? Did i do something wrong or thas the OS that dont like me?

sullrich · Jan 18, 2006, 10:38 PM

try bridging lan -> opt1 instead of the reverse of that.

alexus · Jan 18, 2006, 10:59 PM

no tryed
LAN <-> OPT1
and
LAN -> OPT1

neither of rhem are working….
Did any one got it to work? Why wouldnt u do it as ussually like StarOS has it, you craate the bridge and then assign mac addreses to it and everything works perfectly,,,, but here im going crazy.... whats a point of the router if it doesnt brige the interfaces?

sullrich · Jan 18, 2006, 11:00 PM

Yes it works fine, I have a bridge running here at my home.

Never seen StarOS, didn't know that we where required as developers to copy cat other software…

alexus · Jan 18, 2006, 11:03 PM

um… why it doesnt work here then... are u running EMbedded version?

PS: no u dont have to copy, but its all the same anyway... most of the opensorse modules...

sullrich · Jan 18, 2006, 11:05 PM

@alexus:

um… why it doesnt work here then... are u running EMbedded version?

Not sure, as I said before it works fine here. In fact I just fired up another box and tested it with wireless bridge. Works fine.

@alexus:

Not quite. BSD and Linux are completely different animals.

alexus · Jan 18, 2006, 11:09 PM

lets keep the linux VS bsd discusion for other forum post…

what version do you have on your wrap box?
also do u know thw command to see the bridging tabls for if_bridge?

sullrich · Jan 18, 2006, 11:11 PM

@alexus:

Then don't proclaim that everything is the same. It is not.

@alexus:

what version do you have on your wrap box?

Who said I have a wrap? I have 10+ boxes all of which are on the latest version from http://www.pfsense.com/~sullrich/BETA2-BUGVALIDATION5/

@alexus:

also do u know thw command to see the bridging tabls for if_bridge?

ifconfig

alexus · Jan 18, 2006, 11:18 PM

looks strange too me then… ifconfig sais that the bridge0 is there and is between sis0 and sis2 so it should work i think...

do you know how I can check the bridge functionality in command prompt?

sullrich · Jan 18, 2006, 11:26 PM

Show the contents of ifconfig

Have you rebooted the firewall by chance? How about the client?

alexus · Jan 18, 2006, 11:33 PM

i havent reboot any oh them… getting ipconfig now

sullrich · Jan 18, 2006, 11:34 PM

Try rebooting.

For some reason my iMac will not obtain an IP until I reboot. I really don't know why this is the case and frankly I'm not interested in chasing it down since its such an easy remedy.

alexus · Jan 18, 2006, 11:36 PM

here is ifconfig… and im rebooting in meanwhile...

It's disabled. It won't forward. You have a ethernet loop?</learning,discover,stp>

alexus · Jan 18, 2006, 11:51 PM

i rebooted aint working… and u know that before me lol

what do u mean by loop?
