hi  folks,



I am running OSX server 2.2.1 hosting mail,  and L2TP VPN which work great..


I port forward  port 25



and UDP 500, 1701 , 4500 for the VPN, from my router gateway to my mac mini.





are there any security concerns in relation to having open access to the UDP ports 500,1701, 4500  on my mac mini?




I had tried to put a firewall rule on my gateway  to only allow access from the public ip of my iphone over 3g, but that didnt seem to work  as i still could connect over a different public network, so it appears that the firewall rule was ignored as the traffic was automatically being natted by the gateway..



my main question really, is should i be worried, leaving UDP ports open publically to my mac mini server?
