Cisco ASA5505 with Etisalat Business One

[andy.hessey]

Hello all...

Going around in circles with this one - hope someone can help.

I am currently setting up a new network in Dubai and the company I am installing it for have their internet with Etisalat Business One.

We are going to stick in a new ASA5505 which will act as the NAT boundary to give us an address range of 192.138.x.x

Never having dealt with Etisalat we just need to confirm this will work with their network and how the dynamic IP will present itself to the ASA5505 - or even IF it will present itself.

Their tech-support guys could confirm that Business One comes with a dynamic address but couldn't answer anything beyond that.

Can someone far wiser than I please help?

Many thanks

Andy.

ASA supports 2 methods on getting dynamic ip address on the outside  interface (interface connected to the internet) via ethernet:

1) PPPoE

2) DHCP

Here is the sample configuration for your reference:

PPPoE: http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a0080ab7ce9.shtml

DHCP: http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a00806c1cd5.shtml

(check out the DHCP client configuration section).

You  would need to ask the Internet provider (Etisalat Business One in your  case) whether they are using PPPoE or DHCP to assign the dynamic ip  address.

Hope that helps.
