hi one and all,

Seeing that M0n0, don't support ISDN dial out, put a cisco isdn router to 
dial my ISP, and via m0n0, i made a vpn connection to the head office,

I have the following config..


Network A (HeadOffice)  --> 192.168.9.0
Network B (BranchOffice  --> 192.168.3.0


ISDN BRI interface
DHCP ip from ISP

ISDN Ethernet0
192.168.100.1


M0n0 WAN interface
192.168.100.2

M0n0 LAN interface
192.168.3.254

seeing that this is a DHCP account, at the headoffice, i used the Moblie 
client.

as the Cisco router makes the ISDN connection, i can clearly see that my 
m0m0's, automatically connection the vpn, this is verifed, by directly 
pinging a client on the other side of the tunnel

when i try to ping a client 192.168.9.1 from the 192.168.3.0 network, i'm 
not getting a respond.

on the WAN interface, i have UNTAG the option, to allow RFC1918 ip's ex. 
192.168.x.x

in the firewall i saw that traffic was being block between the 192.168.100.1 
and the 192.168.100.2 interface, i created a rule telling the firewall to 
let all traffc on the WAN interface from 192.168.100.1 to the network thru.

after that was done, i no longer saw the log blocking the ICMP traffic.

but i still ain't getting any response,
does anyone have an off the head answer for this problem, or should i 
provide some more detail information.

thnks
