Hi, I can established a VPN-Connection from the Internet through my Firewall to my VPN-Server (SuSE 8.0 Kernel 2.4.18). The Authenticate works correctly. The only wrong thing is that I loose my connection after a few seconds. Log-File: pppd[22572]: sent [LCP EchoReq id=0x4 magic=0xe5e560e9] pppd[22572]: rcvd [LCP EchoRep id=0x4 magic=0x16f709d7] pppd[22572]: sent [LCP EchoReq id=0x5 magic=0xe5e560e9] pppd[22572]: rcvd [LCP EchoRep id=0x5 magic=0x16f709d7] pppd[22572]: sent [LCP EchoReq id=0x6 magic=0xe5e560e9] pppd[22572]: sent [LCP EchoReq id=0x7 magic=0xe5e560e9] pppd[22572]: sent [LCP EchoReq id=0x8 magic=0xe5e560e9] pppd[22572]: No response to 3 echo-requests pppd[22572]: Serial link appears to be disconnected. pppd[22572]: cbcp_lowerdown pppd[22572]: Script /etc/ppp/ip-down started (pid 22621) Summary of lsmod : ppp_async 6080 0 (autoclean) ppp_mppe 20128 0 ppp_generic 14984 0 [bsd_comp ppp_async ppp_mppe] Last but not least the option-file : name mein_server_name lock mtu 1490 mru 1490 proxyarp auth +chap #+chapms +chapms-v2 ipcp-accept-local ipcp-accept-remote lcp-echo-failure 3 lcp-echo-interval 5 deflate 0 mppe-128 mppe-stateless debug What's wrong with my config?
