Hi, I am trying to configure poptop on OpenBSD 5.3 without success. I've installed the package and configured the files as the /usr/local/share/doc/pkg-readmes/poptop-1.3.4p4 says but didn't work so I started to change things here and there without success. These are the facts:
/etc/pptpd.conf: stimeout 10 noipparam logwtmp localip 5.5.5.1 remoteip 5.5.5.2-102 /etc/ppp/options: lock auth usehostname proxyarp +MSChap-V2 mppe-128 mppe-stateless /etc/ppp/ppp.conf: default: set log Phase Chat LCP IPCP CCP tun command set speed 115200 pptp: set log phase tun enable proxy set dns 8.8.8.8 8.8.4.4 set ifaddr 5.5.5.1 5.5.5.0/0 255.255.255.0 set timeout 0 enable chap enable MSChapV2 And here the error: pptpd[25764]: CTRL: Starting call (launching pppd, opening GRE) ppp[14716]: Phase: Using interface: tun0 ppp[14716]: Phase: deflink: Created in closed state ppp[14716]: tun0: Command: default: set speed 115200 ppp[14716]: tun0: Command: pptp: set log phase tun ppp[14716]: tun0: Phase: PPP Started (direct mode). ppp[14716]: tun0: Phase: bundle: Establish ppp[14716]: tun0: Phase: deflink: closed -> opening ppp[14716]: tun0: Phase: deflink: Connected! ppp[14716]: tun0: Phase: deflink: opening -> carrier ppp[14716]: tun0: Phase: deflink: carrier -> lcp ppp[14716]: tun0: Phase: bundle: Authenticate ppp[14716]: tun0: Phase: deflink: his = none, mine = CHAP 0x81 ppp[14716]: tun0: Phase: Chap Output: CHALLENGE ppp[14716]: tun0: Phase: Chap Input: RESPONSE (49 bytes from testuser) ppp[14716]: tun0: Phase: Chap Output: SUCCESS ppp[14716]: tun0: Phase: deflink: lcp -> open ppp[14716]: tun0: Phase: bundle: Network ppp[14716]: tun0: Phase: deflink: open -> lcp ppp[14716]: tun0: Warning: ff01:4::: Change route failed: errno: Network is unreachable ppp[14716]: tun0: Warning: ff02:4::: Change route failed: errno: Network is unreachable ppp[14716]: tun0: Warning: ff02:4::: Change route failed: errno: Network is unreachable ppp[14716]: tun0: Phase: bundle: Terminate pptpd[25764]: CTRL: EOF or bad error reading ctrl packet length. pptpd[25764]: CTRL: couldn't read packet header (exit) pptpd[25764]: CTRL: CTRL read failed ppp[14716]: tun0: Phase: deflink: read (0): Got zero bytes ppp[14716]: tun0: Phase: deflink: Disconnected! ppp[14716]: tun0: Phase: deflink: Connect time: 1 secs: 354 octets in, 364 octets out ppp[14716]: tun0: Phase: deflink: 7 packets in, 11 packets out ppp[14716]: tun0: Phase: total 718 bytes/sec, peak 0 bytes/sec on Sun Aug 4 18:23:07 2013 ppp[14716]: tun0: Phase: deflink: lcp -> closed ppp[14716]: tun0: Phase: bundle: Dead ppp[14716]: tun0: Phase: PPP Terminated (normal). pptpd[25764]: CTRL: Client <truncated_ip> control connection finished So far I think is not an authentication problem (the authentication process seems to be "success") and it is a network related issue. However, I do not how to fix it according to the three lines on the output: ppp[14716]: tun0: Warning: ff01:4::: Change route failed: errno: Network is unreachable ppp[14716]: tun0: Warning: ff02:4::: Change route failed: errno: Network is unreachable ppp[14716]: tun0: Warning: ff02:4::: Change route failed: errno: Network is unreachable I enabled and applied on sysctl.conf: net.inet.gre.allow=1 net.inet.gre.wccp=1 Also, I added the pf.conf lines needed to allow traffic from 1723 and GRE connections and, to be sure, let all traffic from 5.5.5.0 network pass through the firewall on tun0. Any help? What I am missing? Thanks in advance, Alvaro
