No Internet access while connected with Cisco AnyConnect VPN client

Question

I joined a Cisco IPSEC VPN (based on Group Authentication).

I had to install the VPN using some tricks since is not working anymore on Windows 10.

The problem is that once connected in VPN internet is no working anymore.

This is my route table

I tried to delete the entry: 0.0.0.0 0.0.0.0 10.210.222.65 10.210.222.77 36 since my internet working gateway is 192.168.1.254 but its still not working.

I searched anywhere but nothing was working.

Any ideas?

Have you checked your DNS settings? Please show output for `ping 8.8.8.8` and `ping google.com`. — Alexander Tolkachev, Jan 17 '18 at 22:20
This is the output: PS C:\WINDOWS\system32> nslookup google.com Server: UnKnown Address: 10.210.210.10 It look like it' still using the DNS server of VPN (that i suppose i should keep for resolve name of the VPN). Since i deleted the "route redirect" for internet with this command: route delete 0.0.0.0 mask 0.0.0.0 10.210.222.65 I suppose it should use as gateway this one: 0.0.0.0 0.0.0.0 192.168.1.254 192.168.1.161 55 That is from my real gatweway. Why is not using this network DNS? — Gianluigi Liguori, Jan 18 '18 at 12:44

You don't have access to Internet because your default resolver is DNS provided by AnyConnect. Those DNS couldn't resolve names from Internet. According Cisco forums that issue and routing issue could be fixed only on server side. Sounds like you should talk with your IT team.
