hi,
can someone help me why forwarded packets does not contain
"sackOK,timestamp,nop,wscale"?
Thank you

Following is the case it does not work (when forwarded from gateway):
14:32:05.249347 eth0 < 216.198.139.37.10749 > 192.168.2.2.http: S
66187:66187(0) win 8192 <mss 1360> (DF) [tos 0x10]
14:32:08.169347 eth0 < 216.198.139.37.10749 > 192.168.2.2.http: S
66187:66187(0) win 8192 <mss 1360> (DF) [tos 0x10]
14:32:14.179347 eth0 < 216.198.139.37.10749 > 192.168.2.2.http: S
66187:66187(0) win 8192 <mss 1360> (DF) [tos 0x10]
14:32:26.199347 eth0 < 216.198.139.37.10749 > 192.168.2.2.http: S
66187:66187(0) win 8192 <mss 1360> (DF) [tos 0x10]

Following is the case it works if I try it from the same machine:
