[-- Attachment #1 --] Hi, I am using 4.0-RELEASE to act as a router between my DSL connection and my 3 windows PCs. I connect with PPPoE and use ipfw and nat for bridging and address translation. As I described in my earlier post, most things work, but some particular web sites don't load. Thanks to Marc Silver and Corigan, who suggested I try changing the options for ipfw or the MTU on the windows box, but I still can't get it to work. I've reduced the MTU to 1400 and convinced myself that the firewall is wide open. After staring at tcpdumps for the past few days I don't think it is a datagram size problem; look at the attached files and judge for yourself. One thing I notice is that tcp options like <wscale 0, nop (does that mean no op?), and timestamp> don't seem to show up in the slashdot.fail file, while they do in the slashdot.success file. Any advice appreciated. Thanks, -Tim timothyr@timothyr.net [-- Attachment #2 --] Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll xl0 1500 <Link#1> 00:01:02:48:ad:91 158 0 147 0 0 xl0 1500 10/24 scarlet 158 0 147 0 0 lp0* 1500 <Link#2> 0 0 0 0 0 ep0 1492 <Link#3> 00:c0:4f:da:06:83 2254 0 1693 0 0 ep0 1492 192.168.1 192.168.1.1 2254 0 1693 0 0 sl0* 552 <Link#4> 0 0 0 0 0 ppp0* 1500 <Link#5> 0 0 0 0 0 lo0 16384 <Link#6> 0 0 0 0 0 lo0 16384 127 localhost 0 0 0 0 0 gif0* 1280 <Link#7> 0 0 0 0 0 gif1* 1280 <Link#8> 0 0 0 0 0 gif2* 1280 <Link#9> 0 0 0 0 0 gif3* 1280 <Link#10> 0 0 0 0 0 stf0* 1280 <Link#11> 0 0 0 0 0 faith 1500 <Link#12> 0 0 0 0 0 tun0 1492 <Link#13> 122 0 110 0 0 tun0 1492 165.121 user-2inirrm.ds 122 0 110 0 0 [-- Attachment #3 --] Routing tables Internet: Destination Gateway Flags Netif Expire default 165.121.111.1 UGSc tun0 10/24 link#1 UC xl0 => 127.0.0.1 127.0.0.1 UH lo0 165.121.111.1 165.121.111.118 UH tun0 192.168.1 link#3 UC ep0 => 192.168.1.2 0:a0:c9:ee:e0:c9 UHLW ep0 1144 192.168.1.3 0:0:86:50:46:7f UHLW ep0 478 192.168.1.4 0:0:86:15:ab:f6 UHLW ep0 392 [-- Attachment #4 --] #
