--- Comment #5 from o...@netfusion.fr --- I encounter the same problem in a slightly different configuration: - Hyper-V 2012, hosting: -- FreeBSD 10.2 x64 with MPD acting as a PPTP server -- Windows 7 - Clients on the LAN (misc OS), inclding an old FreeBSD 6.1 - Clients connected to FreeBSD 10.2 VM by PPTP (MPD5) using misc OS as well Firewalls turned off. * TCP, UDP, ICMP work: - between all PPTP clients - between a PPTP client, FreeBSD and the Windows 7 virtual machine - between FreeBSD and local machines on the LAN * TCP doesn't work between a PPTP client and machines on the LAN. I tried to investigate by opening a TCP connection on port 80 from a PPTP client to the old FreeBSD 6.1 on the LAN. There is a part of the tcpdump I ran on that old FreeBSD 6.1: IP (tos 0x0, ttl 127, id 20111, offset 0, flags [DF], proto: TCP (6), length: 48) pc-ed.lan.domain.fr.56026 > srv-mandy.lan.domain.fr.http: S, cksum 0x84d6 (incorrect (-> 0x7c54), 2429810306:2429810306(0) win 8192 <mss 1354,nop,nop,sackOK> I have read that having an incorrect checksum was normal, so I guess the problem doesn't come from that. >From what I saw, the problem occurs as long as the FreeBSD 10.2 is used as a gateway (NAT or not). Let me know if I can do other tests to help you investigate the problem. Any help would be appreciated. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
