Hi,

i finally got pptp and NAT working with the patch for bug #397 
<https://bugzilla.netfilter.org/bugzilla/show_bug.cgi?id=397>.

Two questions left:

- sometimes (every 10th connection attempt or so) the connections fails 
with "GRE: read(fd=5,buffer=8056720,len=8260) from network failed: 
status = -1 error = Protocol
not available" reading in the server logs. I use windows clients with 
linux server. somewhere I read that I should load ip_gre on the firewall 
or block a specific icmp packet, is that correct ? (I dont like to block 
icmp, icmp is there for reason)

- I am unable to estabish two pptp connections from one client, I can 
connect to one pptp server and I can connect to a second pptp server, 
but the second connection never accepts any traffic, when I stop the 
first connection, the second connection begins to work. Is this a bug or 
a known missing feature ?


Thank you very much !
