Can not RDP through VPN

Hello everyone! I'm hoping someone can help me with a little issue I'm having. I picked up a little job that needed help with mobile VPN access. What I was told was it worked, and then it stopped. Which means it could be 1000000 possible reasons. They had an IT firm in there for a while, but I guess they were doing more harm then good. So, I looked over the running config, and saw a few gaps which could defiantly cause some issues with connection. It looks like whoever set it up, possibly wrote the ipsec phase 1 and 2 proposals to startup config, and continued on configuring and didn't save that. So possibly after a reboot of the router, the non saved parts of the config got wiped, and it stopped working. So, my changes where successful and I was able to VPN into the network. Happy dance and all that. I'm able to ping ips on the local subnet, so I assume, from what I was told it was fixed. So I contacted the on site contact, and let him know it was fixed, and as a lesson I learned before, I sent screen shots of it being operational. So I get a call back later, that when they are connected through mobile VPN, they cant RDP into the RDP server. Seemed odd, but I inspected it further... I can telnet, ssh, even access cifs shares from the server, but could not RDP into it. I checked server firewall, AV etc. I looked over ACL's I thought possible it was blocking it there, there are some ACLS for blocking incoming traffic from telneting and RDP. So I rewrote the ACl with allowing the vpn subnet connect via RDP to server. I even went as far as basically wiping the acls, and still could not RDP. By doing this, allowed me to RDP externally from my laptop, which at least proved the server isnt blocking the connecting. So to avoid pulling all my hair out, hoping someone could offer some assistance. I did a google search on this issue, and tried changing MTU on the vpn client, that didnt fix it. And it is configured as split tunnel. So Ill post the running config with original ACL's. F0 is outside interface, local subnet is 192.168.1.0/24 and vpn is 192.168.23.0/24. I pay in beer:)

Well that was an easy fix, this was the culprate -> ip nat inside source static tcp 192.168.1.10 3389 interface FastEthernet0 3389.
