Hi Tom,

Thank you for looking into this. This is what tcpdump outputs when I 
launch a http request:

04:20:08.292735 IP es01.tela-web.com.35200 > ks309069.kimsufi.com.www: S 
3758580123:3758580123(0) win 5840 <mss 1460,sackOK,timestamp 40378785 
0,nop,wscale 5>
04:20:08.293384 IP ks309069.kimsufi.com > es01.tela-web.com: ICMP host 
ks309069.kimsufi.com unreachable - admin prohibited, length 68

And this when I ssh:

04:31:26.138508 IP es01.tela-web.com.35007 > ks309069.kimsufi.com.ssh: . 
ack 958 win 281 <nop,nop,timestamp 41056616 122428939>
04:31:26.141516 IP es01.tela-web.com.35007 > ks309069.kimsufi.com.ssh: P 
838:982(144) ack 958 win 281 <nop,nop,timestamp 41056619 122428939>
04:31:26.146252 IP ks309069.kimsufi.com.ssh > es01.tela-web.com.35007: P 
958:1678(720) ack 982 win 70 <nop,nop,timestamp 122429100 41056619>

Thank you,
Eric.
