Hello,
I have seemingly read everything on the web and tried all options but cannot seem to get a client-to-site VPN to work on this router; pptp, l2tp or ssl.
Ideally I want to have our mostly Mac users be able to use the native OS VPN 'client' connection but am open to Open Source clients as well. We have a few win10 PCs, also IOS and android phones - but those are not as critical.
I set up a dedicated, but with default settings, IPSEC profile (IKEv1) to use with l2tp, I have the default self signed cert for SSL, I have different subnets (192.168.2.1-30 through 192.168.4.1-30) for each of the different types of VPN.
I have users assigned to a group and try logging in as them.
The logs are pretty worthless - not logging much, and the error messages on logging in ('a configuration error occurred' for IKEv1, 'The negotiation with the VPN server failed. Verify the server address and try reconnecting.' for cisco ipsec or 'The L2TP-VPN server did not respond. Try reconnecting. If the problem continues, verify your settings and contact your Administrator.' for l2tp) or are sparse and unhelpful on Googling. Mostly, the logs don't record my attempts to connect.
nmap shows the ports NOT open though the firewall settings show they are (UDP 500, 1701, 1723, 4500).
I SEEM to be able to connect on a PC using the Fortinet ssl VPN client 'connection 40%')- though at the command prompt I dont see any of the other things on the network I think I should. PPTP says I am missing a config file and am beyond my 25 connection limit though I am the only one "ON"...
Any help appreciated on this - Cisco will provide no support and we will not use their AnyConnect client. We actually may just scrap their devices as they are so frustrating to deal with - but I really want to make this work and feel it is a simple configuration issue with crap documentation/support. Can I use wireshark or some other tool to sleuth what is wrong here?
