Hi,
I'm trying to make a small setup with VPN-PPTP.
I have a PopTop server (in my valid network, not behind pfSense). The
problem I have is that when clients behind pfSense try to connect, only
the first one manages to open a tunnel. The second one gets an error
(the client says error 619, "The port was disconnected."). In the PopTop
logs I get the following messages:
Jun 27 10:29:18 server_name pptpd[12198]: GRE:
read(fd=6,buffer=804e560,len=8196) from PTY failed: status = -1 error =
Input/output error, usually
caused by unexpected termination of pppd, check option syntax and pppd logs
Jun 27 10:29:18 server_name pptpd[12198]: CTRL: PTY read or GRE write
failed (pty,gre)=(6,7)
Jun 27 10:29:18 server_name pptpd[12198]: CTRL: Reaping child PPP[12199]
Jun 27 10:29:18 server_name pptpd[12198]: CTRL: Client
pfSense_IP_address control connection finished
I know that PPTP and NAT have a problem in dealing with one another
(actually, it's GRE with NAT). Is there any setup or something alike I
can activate so that pfSense makes this work? With Linux, it's hard but
doable (actually, run /sbin/modprobe/ip_conntrack and a couple other
iptables modules. The pain is to find this out....), but I don't know if
it's possible with FreeBSD/pfSense.
Thank you,
Marcos Roberto Greiner
