Anyconnect ASA cannot access internal network or internet

aparikh — Mon, 11 Mar 2019 23:37:50 GMT

After connecting via anyconnect client 2.5, I cannot access my internal network or internet.

My Host is getting ip address of 10.2.2.1/24 & gw:10.2.2.2

You can add the following:

route outside 10.2.2.0 255.255.255.0 1.21.24.23 1

because you have 10.0.0.0/8 route pointing to the inside.

Also, do you need split tunnel, or are you trying to send all traffic to the ASA? because you have "permit any" for your split tunnel acl, that's why i asked.

If you want to send the VPN internet traffic towards the ASA too, then you need to configure:

nat (outside) 1 10.2.2.0 255.255.255.0

If you want to send the VPN internet traffic directly off local internet, then you would need to configure the correct split tunnel acl to only include subnet behind the ASA.

It did not work.

I added the "

route outside 10.2.2.0 255.255.255.0 1.21.24.23 1"

I also added "access-list split-smart standard permit ip 10.2.2.0 255.255.255.0"

I do not care about the split-tuunel.

Split tunnel ACL is incorrect, you should add the internal LAN subnets, not the VPN pool subnets and also add the correct NONAT ACL.

If you are trying to access the 172.16.1.0/24 subnet, then add the following:

access-list NONAT extended permit ip 172.16.1.0 255.255.255.0 10.2.2.0 255.255.255.0

Then the following split tunnel ACL:

access-list split-smart standard permit ip 172.16.1.0 255.255.255.0

Lastly, try to see if you can ping 172.16.1.200 after adding the above.

It is working.

I added the "address-pool" under the tunnel-group xxx general-attribute"

Thanks for taking time to respond.
