Hello,
I have been working on setting up an external VPN for global protect. The VPN is able to access internet but won't allow me to access internal resources. After speaking with PaloAlto's support team in depth we were not able to find any issues with the VPN configuration and security/nat policies. It was suggested to me to look at the ACL lists in cisco's core but I am having trouble understanding if the IP configured is allowed through or not. Any help would be greatly appreciated.
Current IP/subnet I need allowed into the network is 10.25.0.0/24.
Below is the current access-list configuration:
Standard IP access list 20
10 permit 10.5.1.0, wildcard bits 0.0.0.255
Standard IP access list 90
10 permit 10.20.1.0, wildcard bits 0.0.0.255
20 permit 10.10.2.0, wildcard bits 0.0.0.255 (23214382 matches)
30 permit 10.5.1.0, wildcard bits 0.0.0.255

This shows your access list, but what device is this, where is this ACL applied you need to look at how the traffic coming in or out.
i do not see any ACL have defined specific to that /24 address space, may be it matching different rule with super net to deny i guess.,
how is your network diagram looks like where this host resides ?

The network 10.25.0.0 is definitively not permited anywhere on this ACL.
