Cisco 800 series VPN Site to Site issue
Hello Experts,
Let me start out by saying that I am beginner when it comes to Cisco security. I have managed to get a site-to-site tunnel working between my Cisco 819 ISR router and the corp router, which FYI, I do not have access to. I was provided the information needed to establish the link and was able to get it working using VTI.
The issue I am having currently is that from my internal network (PCs connected in Fa0-3, which all are part of Vlan1), I can not access the FTP/RDP hosts located in the remote network. I can ping the hosts from the lan side and from with in the console it self. When I test telnet ftp using source Tunnel0 & GigabitEtherner0 it works and shows a status letting me know its open.
I am sure I missing something here. Any suggestions are much appreciated.
Remote network/hosts:
10.100.0.0/16
10.118.0.0/24
10.118.0.20 (ftp)
10.100.22.60 (rdp)
10.100.22.50 (rdp)
Below is a sanitized version of config:
To summarize:
- I can ping all hosts on remote network from both console & LAN.
- Using telnet in console to test FTP seems to work but not from LAN.
- Using telnet in console to test RDP does not work nor does it work from LAN.
- The remote hosts offering FTP/RDP I know are functional. We currently have a leased line (T1) that they allowed access to their network and I am able to use remote ftp/rdp. We are getting rid of the leased line and moving, hence the move to site-to-site vpn.
