VPN2S Behind Cisco Router
Sorry if this question has already been asked but couldn't find an answer. I have a VPN2S sat behind a Cisco 887 that is handling the broadband configuration and management.
I have opened port 500 and 4500 UDP to the WAN port IP address on the VPN2S (192.168.1.65). I have then used the wizard to configure the VPN gateway (IPSEC VPN) as a Server role (I'm wanting my laptop and desktop at a co-working space to connect to that location my firewall is at and breakout to the internet from there)
I have then loaded the IPSec VPN client on to my laptop, configured it for Ikey1 but no matter what I do I cannot seem to get it to connect. I have tried connecting internally at the firewall locations, external at the co working space and on a 4G connection.
Error message I get is:
"VPN client gave up the connection. Retry to open the tunnel."
Not sure how to overcome this? Any help with configuration would be much appreciated.
