Subject: PPTP passthrough
Date: Wed, 3 May 2017 12:13:21 +1000 [thread overview]
Message-ID: <6d2c9c2f-2636-9e3f-b8e1-eec95eb02370@suse.com.au> (raw)
PPTP pass-through seems to be broken. When the client tries to connect,
a gre packet is sent but the reply gre packet is dropped at my firewall.
The relevant conntrack dump shows a mismatch between the expected reply
and the packet received, srckey/dstkey do not match. Is that significant?
gre 47 27 src=aaa.bbb.cc.ddd dst=www.xxx.yy.zz srckey=0x0
dstkey=0xb053 [UNREPLIED] src=www.xxx.yy.zz dst=aaa.bbb.cc.ddd
srckey=0xb053 dstkey=0x0 mark=0 use=1
gre 47 27 src=192.168.0.212 dst=aaa.bbb.cc.ddd srckey=0x0
dstkey=0x1380 [UNREPLIED] src=aaa.bbb.cc.ddd dst=www.xxx.yy.zz
srckey=0x1380 dstkey=0x0 mark=0 use=1
