Configuring TA924as a Basic Router

Jump to solution

Hello, I a have a TA924 providing PRI and analog services and I wanted to add the ability to also use the TA as a Router/Firewall. I have been trying to get it working but so far no luck. Currently I have eth0/1 connected to my internet connection and eth0/2 for my LAN on 10.1.88.1. I also have a secondary ip on eth02 as 192.168.88.1. Not sure how to pass traffic to the internet.

Any help would be greatly appreciated.

See added config in bold:

!

interface eth 0/1

  description WAN

  ip address  100.100.100.1  255.255.255.248

  media-gateway ip primary

  ip access-policy Public

  no shutdown

!

!

interface eth 0/2

  description LAN

  ip address  10.1.88.1  255.255.255.0

  no awcp

  ip access-policy Private

  no shutdown

!

!

ip access-list standard allow-all

  remark allow all traffic

  permit any

!

!

ip policy-class Public

  allow list allow-all self

!

!

ip policy-class Private

  nat source list allow-all interface ethernet 0/1 overload policy Public

  allow list allow-all self

!

!

! Note, you have both ip default-gateway 100.100.100.10 and ip route 0.0.0.0 0.0.0.0 100.100.100.1 in your configuration. Remove the ip default-gateway and change ip route 0.0.0.0 0.0.0.0 w.x.y.z to point to your ISP side of the WAN link, not your own interface. Then configure:

ip firewall

Are you using the setup wizard or the CLI? I'd recommend creating VLANs on subinterfaces of eth 0/2 rather than secondary IPs. A copy of the configuration and a summary of what is and isn't working would help.

The basic idea is to create firewall security zones for Public and Private and NAT the private to the Public interface with overload.

Jayh,

Thank you for your response. My current config is working for my PRI and analog fax lines. I actually really only need 1 LAN subnet, but point taken about the VPN. At this point what I am trying to do is putt an IP PBX behind the Adtran to replace the system with the PRI.  I was watching some videos last night regarding an SBC setup, but I imagine that requires a working LAN setup. I am using the CLI but I will use whatever works! I tried duplicating your post from Router is up/up but can't connect to Internet from LAN substituting the interface ppp 1 for eth 0/1 with no success. I also found some similar post as well with no success. I did see the ease of using the firewall wizard I was just paranoid it would mess up more working config and I would loose voice all together. Any help pointing me the correct direction would be great!

Jayh,

Thank you, I was able to borrow an Adtran that was not in production to do some testing. Using the firewall wizard and setting up the route tables, exactly what you were saying, I had success!!!

When using the Adtan for both Voice and Data services, how will the rules we just implemented effect the PRI and Analog Lines on my production system if at all?

Thanks for your suggestions

From a routing standpoint, they won't be affected. It's possible that the LAN data users can negatively impact voice call quality if they saturate the link to your ISP. You can apply quality of service rules to prioritize voice traffic if needed. That's a separate discussion.

Jayh,

I went ahead and used the firewall wizard after applying it I could make outbound calls but lost inbound calls?

Jayh,

I think the Firewall wizard maybe overwrote my ACL's. Started over with CLI and I now can access internet from LAN.
