I would like a second set of eyes, as I believe the issue may be with the AdTran device I am connecting to rather than the ASA.

When I have this set up, I can ping the AdTran Public IP, but have no internet access.

Thank you very much.

Hi,Your ASA's configuration

Hi,

Your ASA's configuration looks fine, and you are able to ping AdTran public IP, however , not able go online.

From the ASA try below command :-

1. Try pinging the gateway first ( ISP modem IP) if it succeeds ping 4.2.2.2 /8.8.8.8

2. If you are not able to ping the gateway and not able to ping 4.2.2.2/8.8.8.8 from the ASA , then issues are with the ISP modem

3. If 4.2.2.2 works from the ASA and then try same from inside hosts.

Thanks,

Prashant Joshi

hi,do you have internet

hi,

do you have internet access when your PC is configured with public IP and is directly behind the adtran device?

try to add a default route to outside on the ASA.

route outside 0.0.0.0 0.0.0.0 <ADTRAN PUBLIC IP>

Thank you and Johnlloyd for

Thank you and Johnlloyd for the response. I am working with the client to do this testing when they are available and will return with results and hopefully mark this question as answered!
