[c-nsp] need help about network

[ann kok]

Hi 

I have problem to access this site eg: outsidewebsite.com
but this machine can work other website

I also tried to use other machine in different network to access the same website (outsidewebsite.com). It works. but those machines are not acessing    outsidewebsite.com in the same network

I am sure there is no firewall and this website won't block any 80 from outside 


I get "incorret" in the tcpdump.

Do you have any idea?

12:38:36.339248 IP (tos 0x8, ttl 64, id 54019, offset 0, flags [DF], proto TCP (6), length 40) 192.168.0.21.33786 > outsidewebsite.com.http: ., cksum 0xe114 (correct), ack 304 win 6432

12:38:36.355895 IP (tos 0x8, ttl 64, id 54020, offset 0, flags [DF], proto TCP (6), length 238) 192.168.0.21.33786 > outsidewebsite.com.http: P, cksum 0xb071 (incorrect (-> 0xf336), 206:404(198) ack 304 win 6432

Thank you
