Following are two traceroutes: one to dns.hacom.net (216.4.181.20) and one to dns2.hacom.net (216.4.181.21). The route to 216.4.181.21 was successful, while the route to 216.4.181.20 is stuck somewhere in sprintlink.net. It only happens with the Linux server masquerading fr my home network. If I connect my laptop directly, it will works. I thought that the ip assigned to the linux server may cause the problem. So I switch the NIC and get a different DHCP server, same problem! Adelphia telneted to the gateway, 24.51.212.1 and has no problem. It looks like to be Linux specific, but how? The routing table is correctly advertised. traceroute to dns.hacom.net (216.4.181.20), 30 hops max, 38 byte packets 1 10.65.84.1 (10.65.84.1) 9.242 ms 12.374 ms 15.426 ms 2 fl-sdad3c4a-65.dad.adelphia.net (24.49.23.65) 17.746 ms 15.039 ms 17.183 ms 3 64.8.31.125 (64.8.31.125) 47.964 ms 40.561 ms 47.359 ms 4 fe1-0-0.spr-ftw-pos-1.adelphia.net (64.8.29.162) 138.661 ms 41.070 ms 47.944 ms 5 sl-gw20-fw-2-3.sprintlink.net (144.232.194.41) 48.364 ms 45.351 ms 47.090 ms 6 sl-bb20-fw-5-0.sprintlink.net (144.232.11.125) 50.856 ms 42.535 ms 47.820 ms 7 sl-bb22-pen-11-0.sprintlink.net (144.232.18.78) 79.054 ms 84.199 ms 84.236 ms 8 sl-bb22-nyc-13-0.sprintlink.net (144.232.9.69) 66.721 ms 60.890 ms 68.291 ms 9 sl-bb23-nyc-8-0.sprintlink.net (144.232.7.14) 70.396 ms 62.796 ms 69.972 ms 10 sl-bb23-nyc-15-0.sprintlink.net (144.232.9.18) 94.287 ms 74.343 ms 80.321 ms 11 sl-bb22-nyc-13-0.sprintlink.net (144.232.9.69) 65.144 ms 64.289 ms 64.685 ms 12 sl-bb23-nyc-8-0.sprintlink.net (144.232.7.14) 69.932 ms 63.067 ms 70.315 ms 13 sl-bb23-nyc-15-0.sprintlink.net (144.232.9.18) 82.727 ms 84.770 ms 83.015 ms 14 sl-bb22-nyc-13-0.sprintlink.net (144.232.9.69) 72.744 ms 65.579 ms 71.351 ms 15 sl-bb23-nyc-8-0.sprintlink.net (144.232.7.14) 73.286 ms 106.366 ms 72.940 ms 16 sl-bb23-nyc-15-0.sprintlink.net (144.232.9.18) 87.285 ms 78.769 ms 83.868 ms 17 sl-bb22-nyc-13-0.sprintlink.net (144.232.9.69) 72.974 ms 72.780 ms 75.784 ms 18 sl-bb23-nyc-8-0.sprintlink.net (144.232.7.14) 142.833 ms 67.493 ms 76.881 ms 19 sl-bb23-nyc-15-0.sprintlink.net (144.232.9.18) 92.978 ms 79.134 ms 88.024 ms 20 sl-bb22-nyc-13-0.sprintlink.net (144.232.9.69) 77.929 ms 67.750 ms 80.347 ms 21 sl-bb23-nyc-8-0.sprintlink.net (144.232.7.14) 75.580 ms 70.055 ms 75.355 ms 22 sl-bb23-nyc-15-0.sprintlink.net (144.232.9.18) 88.074 ms 82.412 ms 86.245 ms 23 sl-bb22-nyc-13-0.sprintlink.net (144.232.9.69) 75.969 ms 70.199 ms 75.380 ms 24 sl-bb23-nyc-8-0.sprintlink.net (144.232.7.14) 77.286 ms 69.914 ms 78.279 ms 25 sl-bb23-nyc-15-0.sprintlink.net (144.232.9.18) 113.669 ms 84.071 ms 92.714 ms 26 sl-bb22-nyc-13-0.sprintlink.net (144.232.9.69) 81.886 ms 73.403 ms 94.604 ms 27 sl-bb23-nyc-8-0.sprintlink.net (144.232.7.14) 79.440 ms 72.782 ms 80.059 ms 28 sl-bb23-nyc-15-0.sprintlink.net (144.232.9.18) 92.001 ms 85.526 ms 90.673 ms 29 sl-bb22-nyc-13-0.sprintlink.net (144.232.9.69) 80.571 ms 78.739 ms 83.074 ms 30 sl-bb23-nyc-8-0.sprintlink.net (144.232.7.14) 85.666 ms 95.761 ms 81.219 ms traceroute to dns2.hacom.net (216.4.181.21), 30 hops max, 38 byte packets 1 10.65.84.1 (10.65.84.1) 8.352 ms 9.037 ms 14.034 ms 2 fl-sdad3c4a-65.dad.adelphia.net (24.49.23.65) 16.064 ms 9.252 ms 15.32 ms 3 64.8.31.125 (64.8.31.125) 47.530 ms 41.461 ms 57.251 ms 4 fe4-0-0.spr-ftw-pos-1.adelphia.net (64.8.29.130) 57.111 ms 41.179 ms 48.646 ms 5 sl-gw20-fw-2-3.sprintlink.net (144.232.194.41) 48.585 ms 40.425 ms 50.109 ms 6 sl-bb20-fw-5-0.sprintlink.net (144.232.11.125) 47.303 ms 41.881 ms 51.956 ms 7 sl-bb22-pen-11-0.sprintlink.net (144.232.18.78) 80.222 ms 73.359 ms 78.647 ms 8 144.232.16.194 (144.232.16.194) 80.862 ms 74.914 ms 78.974 ms 9 144.232.16.193 (144.232.16.193) 86.664 ms 76.198 ms 76.309 ms 10 sl-nap1-pen-4-0-0.sprintlink.net (144.232.5.62) 79.927 ms 73.876 ms 81.323 ms 11 sprint-nap.digex.net (192.157.69.42) 92.660 ms 74.433 ms 81.052 ms 12 * phl2-core2-fa0-1-0.atlas.icix.net (165.117.51.37) 100.002 ms 95.591 ms 13 dca1-core12-s3-3.atlas.icix.net (165.117.52.121) 117.245 ms 96.022 ms * 14 dca1-core11-pos6-0.atlas.icix.net (165.117.48.201) 108.774 ms 104.818 ms 103.362 ms 15 dca6-core4-pos4-0.atlas.icix.net (165.117.52.238) 113.238 ms 103.334 ms 104.544 ms 16 dca6-core5-pos7-0.atlas.icix.net (165.117.48.118) 106.441 ms 102.469 ms 105.221 ms 17 atl1-core3-pos5-0.atlas.icix.net (165.117.48.61) 116.753 ms 113.261 ms 124.491 ms 18 atl1-core4-pos7-0.atlas.icix.net (165.117.48.150) 119.984 ms * 115.053 ms 19 atl1-core2-pos7-0.atlas.icix.net (165.117.48.142) 123.074 ms 123.056 ms 120.070 ms 20 216.2.64.18 (216.2.64.18) 127.020 ms 111.124 ms 122.323 ms 21 10.10.1.2 (10.10.1.2) 128.179 ms 123.011 ms 129.730 ms 22 dns2 (216.4.181.21) 136.490 ms 111.818 ms 116.210 ms Appreciate any comments/suggestions.
