Your problem is that the subnets at each end of the link overlap. 10.0.0.0/24 includes all of the 10.0.0.0/8 networks so the router can't determine the correct destination.

Yes, the policy must exist before the link is established.

Re: Need help with IPSec VPN problems. No connecting

As you're manually specifying a policy you need
generate-policy=no
.

Use main mode unless you really need aggressive mode.

Turn on IKE logging. VPN connection will only be created when there's traffic to encrypt. Ping from a client at one end to an address at the other.

Connection tracking is not required to handle fragments provided the iptables state engine is not turned on. As there's no way to turn the state engine off in RouterOS the end result is you need connection tracking to handle fragments.

RouterOS 2.9 does not handle NAT-T.

Otherwise, for dynamic IP clients use 'generate-policy'=yes in /ip policy peer.

Netbios doesn't use multi-cast for name resolution, in the absence of DNS, WINS or LMhosts it will use broadcast.

No need to forward ESP as NAT-T will be in use. This uses TCP:4500 (you need to check this port).

Seriously consider doing all this on the router. It'll save the NAT-T overhead.

Ports required:

TCP 1723, 4500
UDP 500

One question: why not do the VPN on the router? No need to forward ESP as NAT-T will be in use. This uses TCP4500 (you need to check this port). No need to forward UDP1701 as this is L2TP without ESP encapsulation. Turn on connection tracking and PPTP / GRE service ports in /IP FIREWALL. This should...

Run a protocol analyser (e.g. Ethereal) on the PC. That way you can check the query and the reply. Compare the result to what you get on a PC that works. Some spyware messes with the PC DNS settings but this should be easy to spot from examining the packets.

Does the Procurve show any errors on the 532's port?

Only other thing I can suggest is to reset the config on the 532 and setup the bare minimum to bridge the ports. See if you still have the problem.

No problem with full-duplex that I'm aware of. I was just puzzled why your LAN connection is 10Mbit full-duplex. If your LAN is a switch then that should probably be set to 100Mbit full. If it's a hub, then 10Mbit half.

Just the interface and bridge config would have been sufficient for now :shock:

Two of your links are fixed at 10MBit full-duplex. This is unusual as 10Mbit is usually associated with hubs which are half-duplex.

Agreed. Removing static routes is generally a good idea in an OSPF environment. However, if you wish to maintain a backup default route then you'll need two static routes. Giving the backup an administrative distance above 110 means that it won't normally be used.

The issue is usually that statically configured default routes have a lower administrative distance than routing protocol routes. Cisco define a static route as an AD of 1 and and OSPF route as 110 so the static route will always be used over the dynamic one. To change this behaviour, you need to al...
