Hello everyone,
I'm trying to hook up a pix 515 to SBC DSL.

I am running into some mild trouble.

I want to edit ip config on ethernet0 however nothing doin'.
Suppose my provider gateway is 1.2.3.4 and My ip is 1.2.3.2 with a subnet of 255.255.255.248

My procedure:
config t
interface ethernet0 (no effect)

I found I can 'edit' the ip address and subnet with:
ip address outside 1.2.3.2 255.255.255.248

But this does not let me set the gateway address for this ethernet.

Do I instead need to set the:
route outside 0.0.0.0 0.0.0.0 1.2.3.4?

Do I need to do other configuration changes to make it compatible with SBC DSL?

Thank you,
 
What does a show int e0 show?

This should be everything you need, I assume all the IP Settings are correct... What about when you enter the command...

ping outside (Ip of Router)

I get no response.....

Do I instead need to set the:
route outside 0.0.0.0 0.0.0.0 1.2.3.4? Because I have not yet.

Also, will the router automatically recognize the DSL signal or do I need to do some hand waving and cartwheels?
 
Yes, but if you ping outside (ip) as long as its in the same subnet you should get a response...

You will need a route pointing to your ISP default gateway.

What kind of DSL connection is it? PPPoA or PPPoE? Have they provided a modem or router that connects to the DSL or is the DSL connection directly into the PIX?
 
I'm trying to move off the modem that plugs directly into the dsl line.

I want the cat5 cable to go from the wall to the pix directly.

The signal is RF1483 (Bridged)

No PPP or PPPoE

The DSL router is not passing my VPN traffic very well so I want to eliminate it altogether with a pix Router.

 
Don't think you can do this by plugging into the PIX directly. RFC1483 bridged mode is simply a way of encapsulating Ethernet into an ATM AAL5 header whereby packets are sent using their MAC address (i.e. bridged)

The PIX can terminate some DSL connections directly (e.g. PPPoE) but it looks like your ISP is providing an ATM connection so you will definetly need something in place to interface between the ISP and the PIX.

You don't have to use the modem supplied though. Any decent DSL router should support RFC1483 (bridged) mode. Just make sure it has support for IPSEC passthrough as well for your VPN traffic (assuming your VPN is being run over IPSEC that is)
