Problem with ASA 5508-X

[Maher Abdelshkour]

Hello,

I have installed Cisco Router that is connected to dual German ISPs and ASA 5508-X. The network is as follows:

-----------------------------------------------------------

ISP1                           ISP2

192.168.1.1              192.168.2.1                            

                       |

             Cisco Router (172.16.1.1)

                       | 

             Cisco ASA

                       |        

      Lancom DSL Router (172.16.2.2)

                       |

Exchange server (DHCP) 192.168.0.0/24 <-- Exchange IP is 192.168.0.10

                       |

           Internal Network

-----------------------------------------------------------

The problem

1-Users can connect to exchange from internal network only, but they can't use Outlook Anyconnect from outside.

2-Users can't open OWA from outside.

Any solution?

Thank you in advance

Hi,

A few things.

Presume a static NAT is in place?

How is the Cisco Router routing between ISPs? Default route to ISP 1? Or are you advertising address ranges via BGP to the two ISPs?

Presume OWA has a DNS A record on the public Internet pointing to the correct public IP address that could be on ISP1 or ISP2 - or PI address space advertised out of both ISPs?

There's quite a lot that could be the issue.

Thank you Joel for your reply.

I've figured out the problem, it was from the Lancom router.
