Wireshark traffic capture on Windows (only to CHAP conversation) ** Attachment added: "windows_to_chap.pcap" http://launchpadlibrarian.net/29759679/windows_to_chap.pcap
** Tags added: network-manager-pptp pppd ** Description changed: Binary package hint: ppp Trying to connect to my workplace from Ubuntu without success. Description: Ubuntu karmic (development branch) Release: 9.10 Case #1 ------- Ubuntu 9.10alpha with latest updates. Using NetworkManager with USB Mobile Broadband Modem to connect to internet. Seems like my internet connection is NAT-ed, because web site whatismyipaddress.com reports IP address different from my interface's IP address. All attempts to open VPN connection using network-manager-pptp fails. Modified /etc/ppp/options with no success. Case #2 ------- Windows XP on same laptop with same USB Mobile Broadband Modem. Using ConnectionManager with USB Mobile Broadband Modem tool to connect to internet. Same situaton as in Ubuntu: seems like my connection is NAT-ed. VPN connections is opened successfully using Windows XP built-in VPN connection tool. --- I think this is not a firewall/NAT issue. May be is, but this is not only issue. There is something else: If windows can connect in same situation, i think linux must be able too. I captured network traffic using Wireshark in both cases & compared as far as i can understand. There was some differences. I tried to change pppd options in /etc/ppp/options file to get next pppd conversations as close as i can to Windows case, but without success so far. My be there is another pppd options i must enable/disable (my fault). May be there is missing feature in pppd.
