Time Capsule block Port 22 and 80?? Help

Hi,

I'm trying to setup a web server and SSH on my ubuntu server using time capsule as a router. My current network setup is:

internet --> Linksys BECMU10 (cable modem) --> time capsule --> ubuntu server

However, i am unable to access the webpage and SSH from WAN.

What i've tried so far:

• 
  port forward 80 and 22 on time capsule via airport utility

• 
  reserved a DHCP ip for ubuntu server (10.0.1.201) via airport utility

• 
  enabled NAT Port Mapping Protocol

• 
  port scan using network utility on ubuntu server (10.0.1.201) shows port 22, 80 and 3306 open

• 
  port scan on Linksys BECMU10 (192.168.100.1) shows port 21 and 80 open

• 
  port scan on time capsule (10.0.1.1) does not show port 22 and 80 open even though i've setup port forward for 22 and 80

• 
  if i setup share time capsule disk over internet (public TCP 5678 and private TCP 548) i have no problems accessing time capsule

• 
  i also tried setting up default host at the ubuntu server (10.0.1.201) but no still no access!

It seems that apple configured time capsule to block port 80, 22 ?????

Any help is appreciated!!!
