AnyConnect connects but only with IP

[Guy Jackson]

When I try to connect outside of my infrastructure with AnyConnect using the configured name it will not connect saying unsuccessful name resolution. I can connect by using the IP of the device though.

Once connected I cannot use any resources unless I use their IPs. Share drives cannot be reached by name but have to use IPs, Websites too.

When I use AnyConnect within my infrastructure I do not have these issues.

Do you think the problem is with AnyConnect, the concentrator or a DNS issue outside of the VPN service?

Thanks for any info.

This seem to be an issue with DNS. any chance you could share the any-connet firewall configurations?

Unfortunately I cant at the moment.

I just don't really understand how anyconnect actually establishes the VPN. I feel like there is something simple in the configuration that is maybe pointing or appending the wrong DNS information. When I am connected through the VPN and I run ipconfig, it displays the proper DNS servers though. Just not sure where the problem could be.

Thanks for the reply!!

you said earlier

"When I try to connect outside of my infrastructure with AnyConnect using the configured name it will not connect saying unsuccessful name resolution. I can connect by using the IP of the device though."

did you try to reslove  your ip address into nslookup from cmd command

!

nslookup 8.8.8.8
Server: resolver2.opendns.com
Address: 208.67.220.220

Name: dns.google
Address: 8.8.8.8

It will only resolve when we are connected through AnyConnect.

Hi,

    It looks like either you have a problem with resolving names via DNS, outside of your infrastructure. Look at your DNS server.
