PROBLEM: I'm unable to connect via VPN to our production network while connected to my home wireless network.
ISP router at home
Cisco ASA 5505 firewall
Buffalo wireless router/firewall
Wirelessly connected devices (iPhone and laptop)
- Guest wireless on ASA 5505.
- Guest wireless network on ASA 5505 is 172.16.1.0/24.
- LAN network on ASA 5505 is 172.16.2.0/24.
- Home wireless on Buffalo router.
- Home wireless network on Buffalo is 172.16.3.0/24.
- My PC connected to a switch port on the ASA 5505 can connect via VPN to our production network.
- Devices connecting to the guest wireless on the ASA 5505 can connect via VPN.
- Devices connecting to the home wireless on the Buffalo router can't connect via VPN.
- All devices can connect to various Internet sites, i.e. Yahoo, Google, etc.
- Can you connect to a remote VPN endpoint with several NATs in between?
- Is this a NAT issue of some kind? How would I validate that?
- Am I violating a design best practice?
- What should be my next steps to troubleshoot/resolve this?
- IPSec connectivity works throughout the network.
- PPTP connectivity works through all but the Buffalo wireless.
