ASA AnyConnect VPN can't ping internal network

Computerwiz24
Level 1
Level 1

Hello,

I have a ASA 5505 with a Anyconnect VPN setup. I can get the VPN to connect just fine but I cant ping anything on the internal network. I tried setting up split tunneling but that didn't help so I removed it. My Running config Is below. Any help is greatly appreciated.

Networks

Inside 192.168.100.0 255.255.255.0

Outside 172.10.10.0 255.255.255.0

VPN Pool 10.10.1.0 255.255.255.0

Thank you

If you can ping the inside interface then you should be able to ping the hosts on the inside network.  What type of PC's / servers are on the inside? if they are windows PCs then make sure that the windows firewall allows ICMP or is turned off completely when testing as this will stop the ping.

Is this your full running configuration?  i do not see a default route, but I can only assume you have it configured since AnyConnect connects successfully.

Could you post a full running configuration (sanitized) please.  Based on what you have currently posted.  You could try to add inspect ICMP under the policy map.  something else you could try is add management-access inside and see if you can ping the inside interface of the ASA.

I do not have a default route set. I added the management-access inside. I can now ping the inside interface but if i try to open the asdm on the outside interface through the VPN it will open up to the certificate warning but when i continue it says page can not be found? I still cant see or ping anything on my inside network though. Below is my complete running config

Thank you Marius. When i shut off my Windows 10 firewall the ping goes through and i can open up a network share on that PC. When i turn the firewall back on i cant see the file share nor can i ping the PC. Now i just need to figure out whats blocking the file share and ping.in windows 10 firewall.

Thank you for the help!

Well, at least, your stated vpn pool:

//

VPN Pool 10.10.1.0 255.255.255.0

//

Is not in your http allow list:

//

http 192.168.100.0 255.255.255.0 inside
