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. Routing Everything Through the VPNSo does all your traffic flow through the VPN when you are connected or just traffic to the protected networks?Cisco VPN servers normally send out a list of routes to private networks so you don't end up sending all of yourTraffic through the VPN server. Fotos GeorgiadisSuggested changing the IPSec proposal lifetime within racoon to 24 hours instead of 3600 seconds.(3600 seconds is 1 hour - who knows why people are seeing drops at 45 minutes)Connect to the VPN (so OSX dynamically generates a racoon configuration file)Open Terminal on Mac (Applications -> Utilities-> Terminal)Copy the generated configuration file to /etc/racoon: sudo cp /var/run/racoon/XXXXXX.conf /etc/racoon**where: XXXXXX is the name or ip address of your VPN server**Edit the racoon configuration file with your favorite editor (pico): sudo pico /etc/racoon/racoon.confAt the bottom of the racoon.conf file, comment out the line: # include "/var/run/racoon/*.conf" (by added the "#" to the beginning of the line)And instead include the copied file (which we will edit): include "/etc/racoon/XXXXXX.conf" (don't forget to replace XXXXXX with the actual name of your file)Edit the generated configuration file with your favorite editor (pico): sudo pico /etc/racoon/XXXXXX.confDisable dead peer detection: dpd_delay 0 Change proposal check to claim from obey: proposal_check claim Change the proposed lifetime in each proposal (24 hours instead of 3600 seconds): lifetime time 24 hours *note: make sure you change all the "proposed lifetime" sections and not just one.Disconnect and reconnect (this time racoon will use your custom configuration).Now try using your VPN for more than 45 minutes and it shouldn't drop. DisconnectsDave Ma's VPN would disconnect after 45 minutes of uptime. 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. IfIt is, we would go through 172.131.25.12 which is our VPN.But what if you just wanted to send everything through your VPN connection? We could just delete the first defaultRoute and let everything go over the VPN, but this is presumably dangerous because the encrypted traffic probablyUses the default route to get to the VPN server in the first place. 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.
