This is a pretty common problem with PPTP through firewalls (damn half-brained MS VPN). I had the same problem when I needed to connect 8 PPTP clients to an outside VPN server. To resolve this problem I had to apply the ip_conntrack_pptp, ip_nat_pptp, ip_conntrack_proto_gre patches to iptables source. These patches are best when used with a 2.4 kernel. I believe they are in testing with 2.6, but I wouldn't want to use them that way in a production environment. You can get the patches from www.netfilter.org in the patch-o-matic-ng.
You'll have compile the iptables to support these patches. Then you will have to recompile the linux kernel to build the modules. You'll have to add what you need in Networking Options -> Netfilter Configuration in the Kernel config.
You can get more complete documentation of the whole process on the netfilter howto page

It's not a very fun process but the only one I found that worked to solve this. I was running this on a Fedora Core 1 server because at the time the patch would not work on the 2.6 kernel. It looks like support for 2.6 is in testing now, but I personally wouldn't want to test this in the type of environment you've described.
Half Elf, it's not very helpful to be so rude. He actually gave enough information about the problem with his headline alone. Any one who had experienced this problem would have known instantly what he was talking about.

I tried to patch and recompile the my Kernel (2.6.x) but it failed. Maybe a Patch that supports the newest Kernel will released soon. In the Meanwile we have to change to MS ISA 2003 or live with the Problem that only 1 PPTP and 1 L2TP Connection can be established. :-(
Thank you again for your Support.
