Unable to ping inside network when connected to AnyConnect VPN

plaush
Level 1
Level 1

Hello, I'm a student studying networking and I'm currently trying to learn how VPNs work, I own a ASA 5512-X with a Security Plus License. I decided to use the built-in ASDM wizard to try to get my AnyConnect VPN up and running - from videos online, it seemed very easy.

However, upon connecting to the VPN using my Windows 11 PC, I could only ping my inside interface (192.168.60.1) and nothing else. The strange part is, I'm able to ping my PC using the firewall and 'inside' servers. I'm suspecting that NAT could be an issue but I'm not too sure due to the previously mentioned part. 

Things I've checked:

PC was assigned an IP specified in the pool (192.168.60.200 in my case)

Windows Firewall completely disabled

Another Windows 10 PC

Redoing the VPN Wizard

Startup Config:

@plaush yes, probably a NAT issue....create a NAT exemption rule to ensure traffic between the local and RAVPN network is not unintentially translated. You should change the RAVPN pool network would not be a different network from the LAN. Example:

object network LAN
subnet 192.168.60.0 255.255.255.0
!
object network RAVPN
subnet 192.168.61.192 255.255.255.192
!
nat (switch,outside) source static LAN LAN destination static RAVPN RAVPN
!
ip local pool inside 192.168.61.200-192.168.61.230 mask 255.255.255.0

Change the pool subnet and check again.

The vpn must not share subnet with any FW interface.

Ouhh, I didn't know that! I'll attempt it, thank you for the prompt reply.

Hello, this works perfectly! Thank you so much, you have saved me hours of troubleshooting. I’ll try to understand what each command does now
