Cannot access internal network though AnyConnect SSL VPN, ASA 9.1(6)

chris.curtiss

Level 1

Hello Cisco Support Community,

 

I have a lab that consists of a two virtual environments connected to a 3750-G switch which is connected to a 2901 router which is connected to an ASA 5512-X which is connected to my ISP gateway. I have configured SSL VPN using AnyConnect and can establish a VPN connection to the ASA from outside but once connected I cannot access the internal network resources or access the internet. My network information and ASA configuration is listed below. Thank you very much for any assistance you can offer.

 

ISP Gateway Network: 10.1.10.0 /24

ASA to Router Network: 10.1.40.0 /30

VPN DHCP Pool: 10.1.30.0 /24

Range Network: 10.1.20.0 /24

Development Network: 10.1.10.0 /24

can you please post a diagram of your toplogy.

I added the webvpn | svc enable statement. Still no change.

Diagram attached.

 

Thanks

Chris

Can you confirm this is correct, your diagram shows your public IP on ASA as /30 whereas you have assinged on "outside" interface as /29?

 

 

This was a mistake on the diagram. The outside network is a /29

 

Correct diagram is attached.

Are you able to ping a public IP, such as 4.2.2.2 from the ASA?

Yes I can ping 4.2.2.2

just for temp you may want to allow icmp any any on your ouside acl.

 

access-list outside_access_in line 1 extended permit icmp any any 

 

I can ping your default-gate address but not your ASA's outside address.

 

Can you post output from "show interface GigabitEthernet0/1"

Please copy this line on "config mode" and try it.

 

webvpn
 svc enable

 

thanks
