aku abis install pptpd daemon, trus dah coba jalanin dan forward dari modem
juga udah jalan, di coba di LAN udah bisa, trus di coba dari luar ada yang bisa
ada yang ga,
klo ga bisa ntu di server pptpd nya muncul baris seperti ini:
LCP: timeout sending Config-Requests
trus ku coba capture pake tcpdump hasilnya
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
$ sudo tcpdump -i eth1 -vv tcp port 1723 or 47
tcpdump: listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes

kira2 kenapa ya, padahal hasil capture nya udah ada :
(1:Successful channel establishment)
berarti udah sukses kan harus nya, tapi kenapa client nya ga bisa2 connect?
kira2 settingan yang salah nya dimana ya?
isi file /etc/pptpd.conf nya adalah:
speed 115200
option /etc/ppp/pptpd-options
stimeout 10
debug
localip 172.16.1.11
remoteip 172.16.1.200-230
dan isi /etc/ppp/pptpd-options nya adalah:
lock
nopcomp
noauth
debug
defaultroute
name pptpd
proxyarp
asyncmap 0
refuse-chap
refuse-mschap
require-mschap-v2
require-mppe
lcp-echo-failure 30
lcp-echo-interval 5
ipcp-accept-local
ipcp-accept-remote
ms-dns 172.16.1.10
ms-wins 172.16.1.10
proxyarp
debug
dump
kira2 salah settingannya dimana ya sehingga ga bisa connect?
thx
