i have windows firewall off
i have colinux 0.7.8 with ubuntu 9.04
i can ping 10.0.2.2 and 10.0.2.15 and the local host ip which is 192.168.5.139
i cannot ping the local host default gateway which is 192.168.5.1
What am I missing?
You never (mostly) can ping any other address that not starts with 10.0.2.x. SLiRP is a firewall and full NAT, the address translation inside SLiRP. Only supported protocols are TCP and UDP packets. ICMP control packets like ping are blocked (better speak: Not programmed).
For testing the Internet access you must use any other programs. For example
