Is 10.6.195.35 being blocked by some iptables rule or other deny rule at 10.6.194.200?
Is 10.6.195.XXX considered to be some other subnet than 10.6.194.XXX that 10.6.194.200 doesn't like?
I notice some different options in the two sources of SYN requests, but I didn't look deeper to understand if it matters or not.
