PPTP connections would work, though.Finally, the mode config message is transmitted, and the client will handle routing appropriate networks into the VPN tunnel. Apt-get install racoon on.

Kill it by running "ActivityMonitor" in the "Utilities" folder, finding it in the process list and clicking "Quit Process" at the upper leftLook in your system.log by running the Console app for hints at what might be going wrong. So in this case, ifThe destination isn't within 10.1/16 (which means 10.1.*.*) we will go through our default route of 192.168.1.1. If a destination isn'tExplicitly matched below, the traffic will flow through the first default route from the top. So when sending data to 10.1.2.3, I am going through the VPN and that traffic is encrypted.So how does it know what gateway to use for different IPs? Let's take a look at the routing table:I've lopped off a bunch of irrelevant lines but as you can see we have two "default" routes. Let's take aLook at what gateway is used when sending traffic to apple.com from within the Terminal application:Recvpipe sendpipe ssthresh rtt,msec rttvar hopcount mtuNotice the "gateway" line there? Traffic to apple.com is going out 192.168.1.1 which is my normal Internet gatewayLet's try an IP on a protected private network: (10.1.2.3)In this case, the gateway is 172.131.25.12 which is a fake IP on the far end of the VPN which will eventually routeTraffic to 10.1.2.3. The reasoning behind this is why protect it if the traffic is destined for an insecureNetwork anyway? The native OS X Cisco VPN adds these routes automatically and removes them when you disconnect.That's one of the things that differentiates the Cisco VPN client from the standard IPSec client. Go into offline mode on steam for macA reboot should be yourWeapon of last resort to get your networking back but you might also want to print these instructions out so you haveNow let's do the dangerous bit and rip the first default route away:Now let's check to see if we can still get to our VPN server:Now let's look at the wider Internet by seeing how we get to apple.com: (17.172.224.47 - we aren't usingApple.com here because we don't want to depend on DNS working)Route: writing to routing socket: not in tableWhoops, something is wrong! That's because that first route there is a little deceptive. (1.2.3.4) You will notice above that my Cisco VPN server adds this route automatically,But if yours isn't configured that way you can add it like this:It is safe to try this if you already have the route because the command will just fail.The next thing we are going to do is a little dangerous and remove all your network access. So if we are going to remove the default route to 192.168.1.1, we have to make sure we have an explicitRoute below to the VPN server. ![]()
