Now, here is a real problem. We have 6 IP addresses. 203.147.165.112 to 119 with netmask 255.255.255.248 We have used three. One for the mail server and one for the DSL router and one for proxy server. Switch _______________ | | | | | | | | | | | ---- DSL Router ---- Internet | | | | | 203.147.175.113 | | | | | | | | | ------- Proxy Server (multihomed) | | | | 203.147.165.114 | | | | 192.168.10.4 | | | | | | | ----------Mail Server (multihomed) | | | 203.147.175.116 | | | 192.168.10.3 | | | | | -------- 192.168.10.5 (A) Linux machine | ----------- 192.168.10.6 (B) windows machine ---------------- Hub & computers of address 192.168.10.* My Linux Machine shown as (A) in the diagram cannot connect to the internet. In fact, it does not even ping to DSL Router 203.147.175.113 On another windows macine (192.168.10.6) it is happily accessing Internet thru proxy server. Here is my routing table on Linux Machine. Kernel IP routing table Destination Gateway Genmask Flags MSS S Window irtt Iface 203.147.175.112 0.0.0.0 255.255.255.248 U 0 0 0 eth0 192.168.10.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 203.147.175.113 0.0.0.0 UG 0 0 0 eth0 What is wrong with this table, and why can I not ping 203.147.175.113. I have done "echo 1 > /proc/sys/net/ipv4/ip_forward I have also set proxy as 192.168.10.4. By the way, I comapred this table with mail server (192.168.10.3) routing table. And it resembles it competely. From othe mail server I can ping DSL router (113). But from Linux Machine I cannot do so.
