It makes you look lame :-) */ Hi, I followed the Linux IP Masquerade mini-HOWTO (ver 1.77) to create a gateway over the ppp-connection for my linux client. When the gateway is connected almost everything works ok but I have serious problems when the gateway is not connected to the internet. The internal client doesn't get any message that any machine outside my LAN isn't reachable. For example: Running ping on the gateway machine: PING 62.104.217.71 (62.104.217.71): 56 data bytes ping: sendto: Network is unreachable ping: wrote 62.104.217.71 64 chars, ret=-1 which is totally ok, but running ping on my client: ping 62.104.217.71 PING 62.104.217.71 (62.104.217.71): 56 data bytes --- 62.104.217.71 ping statistics --- 5 packets transmitted, 0 packets received, 100% packet loss (no output after the first two lines, I hit Ctrl-C) As a result of this problem all apps which makes some request (f.i. DNS) stopped until the timeout. Netscape takes minutes to start, sendmail also takes one minute to start (which delays my boot time)... When I removed the default gateway route, everything works ok again (no timeouts...). An other thing I noticed was, even when connected: netscape crashes often (really more often than normal), perhaps this is related to this problem. I'm not sure this is the right place for this problem but I have no idea where to look else and I hope find some help here or at least an URL (or so) where to find help. My idea is that the ICMP-packets don't get back to the client but I don't know if this is possible nor to fix it.
