I have an ASA 5520 setup at home, it is straight onto the internnet via PPPoE and its ste up with mulitple VLANs and is linked straight to my Juniper switch with sub interfaces.

 

The ASA also has DHCP scoopes set up for each VLAN.  This is all working perfectly.  The only issue is that i need to created some static IPs which I know the ASA cant do.

 

My idea is to somehow use my old 887VA router just as a DHCP server but i am unsure how to link this in with my current setup, I have set the DHCP scopes up on the 887VA just unsure how to link it in to the ASA.

You need to setup IP helpers to relay the dhcp info from each vlan to your dhcp server.

here this should help

Thanks for the reply, this is along the lnes i was thinking, but that example is using a layer 3 link between the ASA and the 887VA, but the 887VA can't have a layer 3 port just layer two. Any different ideas?

Huh?

 

Your dhcpd has an IP right... Your different vlans clearly have SVI's on them... How do you think your going to run a dhcpd without an IP?  So that IP (layer3) is going to sit in one of your layer2 vlans.

ok i get that point but how do setup the link betwwen the 887 and the asa? the asa will only allow an ip or sub interfaces (i cant use the subinterfaces as they are already used going to the switch) and the 887 will only allow 1 vlan as access port or a trunked port

HUH??

 

If its on vlan 100.. Then its connected to vlan 100..

 

Draw up how you have this all connected... You have a vlan switch right??? Your dhcp that understands multiple scopes would only need to be in 1 network.. Ie vlan 100... When the ASA relays the dhcp discover it will include the vlan it is coming from say vlan 90...

 

Just google how dhcp relay works... There is as much info on this for how far down the rabbit hole you need to go..

Yeah wasn't sure on how DHCP relay works, i know about using ip helper addresses on SVI's but thats about it, I am getting what you have said here though and have gon of this to try to configure this.  I have configured the 887 as a DHCP server with the scopes for all vlans, i have given it vlan 100 with an ip and set the port to access on vlan 100 along with the switchport too.

 

I can ping the 887 from the ASA and i sdisabled the dhcp scopes on the asa and set the 887 ip up in the relay section of the asdm and ticked the boxes to relay the requests bit it still did not work.  i have attached the configs and a viso diagram of how its connected up. Hope you can help me here.

Where is your helper entry?  Never going to work without that..

 

I see no dhcprelay entries - so how do you think it would work?

 

The article I linked too has everything you need!

Does it need a helper entry being that the asa is the dhcp server and it can see all networks?  I don't think it will hurt, I don't think it is needed.  When configuring local dhcp on a baby asa 5505 or pix 501, I don't remember needing it (it has been a long while).

I think there is other information missing from the dhcp scopes.  

 

default router is missing in all scopes...going to need that if you want the vlans to communicate outside of themselves, like to the internet or to other vlans.

 

 

 

The asa can't create static IPs?  you mean create reservations? The asa really isn't a good dhcp server.  It does a job, but not a great job.  I would have your dhcp done elsewhere and point your helpers there...dhcp may be better on the switch, or even better on a *nix server, or a windows server.

He wants a dhcp server to do all the dhcp for his vlans because the ASA can not do reservations... So if he sets up a dhcp server somewhere on the network with all the scopes... Then his ASA needs to do dhcp relay to get the dhcp discover to the dhcpd..

 

His ASA needs to setup dhcprelay...

 

I sent him a link on EXACTLY how to do what he asked... To be honest  confused why this thread is more than his post and my response long ;)

 

Ok - should of been the 3 posts.. His ?, My Answer and then his Thanks! ;)

 

@sc302 hey mod can you edit his posts to put his configs inside a text box or something so they are not so freaking long for the whole thread.

put it into spoiler tags, you can view as needed.  

 

On the ASA, I would suggest taking out code that isn't needed.   The dhcpd needs to be modified if utilizing in the asa or taken out if not.  If utilizing a dhcp server that isn't the ASA, you need to utilize dhcp helper.

Dont appreciate your aragance at all, i am trying to get some decent help here not be treated like dirt on the bottom of your shoe

 

I cant get in to the CLI because my console port has stopped giving any output for some reason, the telnet/ssh does not let me login says i have the wrong password so i am left with just trying to get the relay working via the ASDM which i have tried but this did not work which i did say in a previous post

Don't take it that way. BudMan is helping you. You aren't listening. I had to learn this myself. Once you start talking his language, it clicks.

Bottom of my shoe?  What -- dude get overself please...

 

What part are you not understanding about the doc linked too?  And we can help... But all the info you need to setup a relay has been given. 

 

If you can not get to console - I would worry about that before working on changing your dhcp config.

Fair enough so any ideas why my console would just stop working, i can get on to other equipment no problem its just the ASA that wont let me on, i coud try to factory wipe it but then i am worried that if i still cant get on to it i wont be able to set it up again

Could be that it doesn’t have a domain name. Could be that you deleted your ssh keys.  Could be that you are on an unsupported version of ssh where your client won’t connect.  Could be that you are using the wrong settings if you are using a console cable.  

 

Or it could be that you don’t have vty 5 15 defined so you can edit via ssh.

Did the console ever work? 

 

Why do you have

no modem enable on your con 0?

 

I would wipe the thing and start with clean config.
