RE: IPENCAP issue
I want to thank everyone for their replies to this. When I first composed this I was trying to get a handle on how to describe the problem let alone fix it. I apologize for not including more details. Here is the layout Wireless cloud network 192.168.0.0/27 192.168.0.1-192.168.0.30(usable addresses) Building A network 10.114.252.0/22 10.114.252.1-10.114.255.254(usable addresses) Building B network 10.114.96.0/24 10.114.96.1-10.114.111.254(usable addresses) Client computer I have been testing from this machine to the Internet via Mozilla Firebird 1.71 Running Mac OS X 10.3.2(also tried a Windows 2000 machine here) IP: 10.114.96.253 DG: 10.114.96.1 Building B FreeBSD 5.1 router LAN IP: 10.114.96.1 DG: 10.114.252.1 External IP: 192.168.0.6/27 Building A FreeBSD 5.1 router External IP: 192.168.0.3/27 DG: 10.114.255.254 LAN IP: 10.114.252.1 Internet router(Cisco 2501) IP: 10.114.255.254 DG: ISP provided Here is my test, I configured the Mac OS X machine to connect to the Building B FreeBSD router and access www.sears.com The machine connects to the site and in the browser displays the HTML title to the site but hangs forever waiting to connect to the site. Note: All these sites work from a machine connected to Building A on the 10.114.252.0/22 network and going out the 10.114.255.254 gateway. I have tried other sides and the sites that appear to work are ones that contain a single A record for their webserver like freebsd.org, ebay.com, cisco.com. When a site has more that 1 A record I get the same behavior as described above examples: sears.com, drudgereport.com, microsoft.com and msnbc.com Here are tcpdumps from 3 places within this test network, I do have the raw files if anyone wants them email me offlist Tcpdump from Building A Description: This tcpdump was done on the FreeBSD router located at 10.114.252.1/192.168.0.3 Frame 1 (62 bytes on wire, 62 bytes captured) Ethernet II, Src: 00:04:75:e8:8b:51, Dst: 00:30:94:e5:bb:23 Internet Protocol, Src Addr: 10.114.96.253 (10.114.96.253), Dst Addr: 129.33.131.219 (129.33.131.219) Transmission Control Protocol, Src Port: 1156 (1156), Dst Port: http (80), Seq: 0, Ack: 0, Len: 0 Frame 2 (62 bytes on wire, 62 bytes captured) Ethernet II, Src: 00:30:94:e5:bb:23, Dst: 00:04:75:e8:8b:51 Internet Protocol, Src Addr: 129.33.131.219 (129.33.131.219), Dst Addr: 10.114.96.253 (10.114.96.253) Transmission Control Protocol, Src Port: http (80), Dst Port: 1156 (1156), Seq: 0, Ack: 1, Len: 0 Frame 3 (54 bytes on wire, 54 bytes captured) Ethernet II, Src: 00:04:75:e8:8b:51, Dst: 00:30:94:e5:bb:23 Internet Protocol, Src Addr: 10.114.96.253 (10.114.96.253), Dst Addr: 129.33.131.219 (129.33.131.219) Transmission Control Protocol, Src Port: 1156 (1156), Dst Port: http (80), Seq: 1, Ack: 1, Len: 0 Frame 4 (798 bytes on wire, 96 bytes captured) Ethernet II, Src: 00:04:75:e8:8b:51, Dst: 00:30:94:e5:bb:23 Internet Protocol, Src Addr: 10.114.96.253 (10.114.96.253), Dst Addr: 129.33.131.219 (129.33.131.219) Transmission Control Protocol, Src Port: 1156 (1156), Dst Port: http (80), Seq: 1, Ack: 1, Len: 744 Hypertext Transfer Protocol Frame 5 (60 bytes on wire, 60 bytes captured) Ethernet II, Src: 00:30:94:e5:bb:23, Dst: 00:04:75:e8:8b:51 Internet Protocol, Src Addr: 129.33.131.219 (129.33.131.219), Dst Addr: 10.114.96.253 (10.114.96.253) Transmission Control Protocol, Src Port: http (80), Dst Port: 1156 (1156), Seq: 1, Ack: 745, Len: 0 Frame 6 (646 bytes on wire, 96 bytes captured) Ethernet II, Src: 00:30:94:e5:bb:23, Dst: 00:04:75:e8:8b:51 Internet Protocol, Src Addr: 129.33.131.219 (129.33.131.219), Dst Addr: 10.114.96.253 (10.114.96.253) Transmission Control Protocol, Src Port: http (80), Dst Port: 1156 (1156), Seq: 1, Ack: 745, Len: 592 Hypertext Transfer Protocol Frame 7 (255 bytes on wire, 96 bytes captured) Ethernet II, Src: 00:30:94:e5:bb:23, Dst: 00:04:75:e8:8b:51 Internet Protocol, Src Addr: 129.33.131.219 (129.33.131.219), Dst Addr: 10.114.96.253 (10.114.96.253) Transmission Control Protocol, Src Port: http (80), Dst Port: 1156 (1156), Seq: 593, Ack: 745, Len: 201 Hypertext Transfer Protocol Frame 8 (60 bytes on wire, 60 bytes captured) Ethernet II, Src: 00:30:94:e5:bb:23, Dst: 00:04:75:e8:8b:51 Internet Protocol, Src Addr: 129.33.131.219 (129.33.131.219), Dst Addr: 10.114.96.253 (10.114.96.253) Transmission Control Protocol, Src Port: http (80), Dst Port: 1156 (1156), Seq: 794, Ack: 745, Len: 0 Frame 9 (54 bytes on wire, 54 bytes captured) Ethernet II, Src: 00:04:75:e8:8b:51, Dst: 00:30:94:e5:bb:23 Internet Protocol, Src Addr: 10.114.96.253 (10.114.96.253), Dst Addr: 129.33.131.219 (129.33.131.219) Transmission Control Protocol, Src Port: 1156 (1156), Dst Port: http (80), Seq: 745, Ack: 794, Len: 0 Frame 10 (54 bytes on wire, 54 bytes captured) Ethernet II, Src: 00:04:75:e8:8b:51, Dst: 00:30:94:e5:bb:23 Internet Protocol, Src Addr: 10.114.96.253 (10.114.96.253), Dst Addr: 129.33.131.219 (129.33.131.219) Transmission
