Reverse resolution from a private subnet to another private subnet

I think I'm having a reverse resolution problem with a workstation that =
resides on a private subnet that tries to connect to a server in another =
private subnet.=20
Here is the topology:
workstation 192.168.0.211
|
firewall A 192.168.0.1(gateway) - 207.156.7.121
|
firewall B 207.156.7.1 (gateway) 172.16.21.103
|
cisco switch/router 172.16.3.119 (gateway)
|
cisco switch/router 192.168.100.60
All of the systems can access my DNS servers, both DNS servers (master and =
slave) have forward and reverse entries for the 192.168.0.211 and =
192.168.100.60. The 192.168.0.x is a Masqeraded subnet behind Firewall A. =
The 207.x, 172.x, and 192.168.100.x subnets are accessable by all =
systems.=20
The problem is when I try to connect to a web service on 192.168.100.60 =
from 192.168.0.211 it takes 30 seconds to get the login. But when I try =
from Firewall A, any machine in the 207.x, 172.x, or 192.168.100.x subnet =
it responds in less than 5 seconds.
Is this a problem were the web server 192.168.100.60 cannot directly =
access 192.168.0.211 since 192.168.0.x is a hidden subnet?
