DHCP scope limitations for ASA5505

So here is the jist,

I have a ASA5505 that i have running asdm 6.4 on it and have tried setting up some DHCP scopes for the interfaces.

I have the security plus key.

I set up 4 interfaces all with different subnets and all with different DHCP being doled out by the firewall for the timebeing.

Anyway, 3 of the 4 work.

I have tried to change interfaces wondering if there was an issue with that phy device.

I tried enableing the subnet that would not work first and it didnt matter still would not issue dhcp.

the other 3 work fine.

Is there a limitation to the amount of scopes that will issue dhcp for an asa5505 ?

Thanks.

Hi,

You should be able to configure DHCP on every interface of the ASA

Only thing that comes to mind fast regarding the ASA5505 model specifically is that it might have a licensed user limit and therefore might not let you configure large DHCP pools.

Though I think it should warn of this.

Can you share the interface and DHCP configurations?

thats the liscensing that i have.

As far as the networks.

lets say they are as follows

10.10.5.0/24-Service net
10.20.5.0/24 - DB net
192.168.5.0/24 - Internal
and the one that doe not work

172.16.5.0/24 Outside

I did not follow the standard on addressing i was just creating some lab envrionments but still didnt htink i would be limited.

Hi,

Could you share the ASA configurations so I can go through them.
