hi all, we have an ascend server that serves a dial up customer sitting on 203.28.51.128.
routing table on the ascend server: 203.28.51.128/27 203.28.51.128 wan12 rGT 120 2 6575 5169 203.28.51.128/32 203.28.51.128 wan12 rT 60 1 4150 5169 they are given the 203.28.51.128/27 subnet from radius. on the customers end is a linux box acting as a router for their /27 subnet. ifconfig on the debian box shows: lo Link encap:Local Loopback inet addr:127.0.0.1 Bcast:127.255.255.255 Mask:255.0.0.0 UP BROADCAST LOOPBACK RUNNING MTU:3584 Metric:1 RX packets:7607 errors:0 dropped:0 overruns:0 TX packets:7607 errors:0 dropped:0 overruns:0 eth0 Link encap:Ethernet HWaddr 00:00:E8:47:F3:9C inet addr:203.28.51.128 Bcast:203.28.51.159 Mask:255.255.255.224 UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:85592 errors:0 dropped:23 overruns:0 TX packets:6940 errors:0 dropped:0 overruns:0 Interrupt:9 Base address:0x240 ppp0 Link encap:Point-to-Point Protocol inet addr:203.28.51.128 P-t-P:203.63.219.10 Mask:255.255.255.224 UP POINTOPOINT RUNNING MTU:1524 Metric:1 RX packets:10757 errors:0 dropped:0 overruns:0 TX packets:10410 errors:0 dropped:0 overruns:0 And netstat -rn on the box shows: Destination Gateway Genmask Flags MSS Window irtt Iface 203.63.219.10 0.0.0.0 255.255.255.255 UH 1524 0 0 ppp0 203.28.51.128 0.0.0.0 255.255.255.224 U 1500 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 3584 0 0 lo 0.0.0.0 203.63.219.10 0.0.0.0 UG 1524 0 0 ppp0 The .128 gateway works fine. All the internal machines work fine *however* they cannot ping the 203.28.51.128 gateway! I've done a ping to one of the machines from the gateway (and a tcpdump) and it seems that the ping packet goes out but never comes back. Should i be looking at the routing tables for the windows boxes? Or does the problem lie on the linux box? Thanks for the help! marc.
