Hi
Can anybody please help?
Am a relative newbie to VPN and am struggling...
I have setup an Astaro firewall mainly for VPN use and am trying to connect from a standard Windows XP client using PSK (this should be simple?)
The config is:
RoadWarrior client (192.168.123.xxx)
|
ADSL router (81.137.180.xxx)
|
Internet
|
ADSL router (81.174.248.xxx)
|
ASL eth0 (192.168.0.xxx)
I have setup the virtual pool with the appropriate PSK under the VPN Connections menu.
I have setup the client as per the L2TP roadwarrior instructions, discovered about the "uncheck" security box, patched the client with the NAT-T patch and still can't get it to work.
I have been able to connect from outside the firewall (but inside the router) using an address in the 192.168.0.0/24 range, so it seems to be basically working.
However when connecting from the Roadwarrior at the remote location the IPSec negotiation doesn't succeed and I can't for the life of me find out why (despite trawling the posts here for more hours than I care to think about)
I have looked in the ipsec.log, it detects that both sides are NATed:
2004:09:29-19:17:28 host pluto[2667]: "S_WindowsRemote_1"[158] 81.137.180.xxx #99: NAT-Traversal: Result using draft-ietf-ipsec-nat-t-ike-02/03: both are NATed
but then gives me the following error:
2004:09:29-19:17:28 host pluto[2667]: "S_WindowsRemote_1"[159] 81.137.180.xxx:64421 #99: sent MR3, ISAKMP SA established
2004:09:29-19:17:28 host pluto[2667]: "S_WindowsRemote_1"[159] 81.137.180.xxx:64421 #99: cannot respond to IPsec SA request because no connection is known for 81.174.248.xxx/32===192.168.0.xxx:4500:17/1701...81.137.180.xxx:64421[]:17/%any{}
I have seen lots of posts about left/right config and subnets and wonder if this is what I am experiencing? Or is it something to do with the NAT traversal.
Eitherway the only way to fix seems to be to hand crank ipsec.conf which I am reluctant to do unless really required.
Any help really, really appreciated. It's driving me nuts
Thanks
