Problem with RWW, can list computers/servers, cannot get logged in

Server01: SBS Premium/ISA 2004 with product fully installed and all service
packs and updates current
Server02: Server 2003 with all SP and updates current
Workstation 01: WinXP Pro SP2 and updates current
Internet access: via Cable modem to Linksys WRT54G

WRT54G: WanIP set by isp, LanIP set to 192.168.30.1; PPTP and IPSec on
passthru; forwarding 1723,443,444,3389 and 4125 to 192.168.30.10

Server01 has two adapters: WanAdapter 192.168.30.10 with only tcpip enabled,
dns to LanAdapter's IP; LanAdapter 192.168.20.100 with tcpip/client/file and
printer sharing enabled; verified Advanced Setting re: binding Lan 1st, Wan
2nd (shows remote connections 3rd??)

When I say "outside the network" I mean accessing the network via a separate
fourth computer (WinXP Pro SP2) using dialup via a different ISP than the one
to which the network in connected.

I can use all of RWW on the intranet, but not (all of RWW) from the outside
network. I can connect to all 3 computers, one to the other via RWW, from
inside the network.

>From outside the network I successfully connect via www address and get RWW
login, login succeeds and everything works, including showing the list of
computers and/or servers (depending who I login as and what permissions,
servers for admin's only) BUT, once I select a computer to connect to I get
one of two errors at the remote desktop, both start with "VBScript: Remote
Desktop Disconnected".

Error One: The client could not establis a connection to the remote
computer. The most likely causes for this error are:
And then is lists remote connections enabled, max. number of
connections, network error, RWW port blocked by firewall
Error Two: The client could not connect to the remote computer. Remote
connection might not be enabled or the computer might be too bust to accept
new connections. It is also possible that network problems are preventing
your connection. Please try connecting again later. If the problem continues
to occur, contact your system administrator.

I can VPN and Remote Desktop all three computers from outside the network.

Other things I have checked/done:
1. Disabled the firewall in the Linksys, let all traffic through
2. Upped connection limits in ISA from 40 to 160 as per MS Q555368
3. Even turned off connection limits in ISA General...
4. Verified User permission to the Remote Desktop on all three computers.
5. A complete scratch reinstall of SBS and got back to the same issue.
6. Monitored and reviewed the ISA logs interactively and reviewed the log
files for errors. The only denial I see, is 2 sets of IGMP packets that come
from the Lan side of the Linksys/router (192.168.30.1) and are going to
224.0.0.1/224.0.0.2. A bit of the log follows: (sorry for the wrapping....)
Just a little discussion more below the log.

I have read tons of posts and searched the web on this issue and would
welcome any suggestions for trouble shooting. It sure appears the 4125 and
3389 ports are open as they generate log activity in ISA.

Thanks for taking the time to read my post.
