Hi I've been using linux to give VPN access to my corporate LAN using the following software: Centos 5.2 x86 kernel 2.6.18-92.1.18.el5xen pptpd (poptop) 1.3.4 ppp 2.4.4 The Centos server has directly connected the Internet Router, on one interface (eth1) and the LAN on another (eth0) and it works as the firewall/VPN server of my LAN. It mostly works, however, if I try to connect using remote desktop (terminal services) to our windows domain controller (for example, it will happen with any windows server) the Centos server will just reboot. I can connect to the windows, authenticate, and work for about 5-10 seconds before the linux reboots. It's not a friendly reboot, it just crashes and restarts. This linux is running virtualized with xenserver express, and the windows domain controller is running as another virtual machine in the same physical computer. I've updated the CentOS server, using yum update but it will still crash. I tried installing pptpd from source, but still crashes the same way. I googled a bit, and somebody said it had a similar issue but solved it lowering the MTU in the WAN interface of the VPN server. I did it, but nothing helped. I've searched bug reports on this, but there seems to be none. Any idea what can I do to fix this? or does anybody know another good VPN server for linux? (I know about openvpn and using ipsec+xl2tpd but these require additional software on the client or are not very linux-friendly). My main requiements for the VPN server are: - it should require no additional software on the windows clients (Vista and XP currently) - it should work fine with Mac OS X and linux clients - if posible, not very hard to setup ;) Thanks a lot, and sorry for the long post. -- Cordialmente, GERMAN ANDRES PULIDO F.
