I have established a site-to-site vpn using 2 ISA 2004 (L2TP/IPSEC). The
problem is that I can Access the second branch from the isa server itself
but if I try to access the second branch from any another pc on my network
it fails.
e.g.: If I try to ping or use a dns server on the main branch I get in the
logging: Denied.

My scenario is that I’m trying to install a child domain in a remote site.
I’m connecting the two sites with my ISA servers 2004. I want to allow all
traffic from both sites. I have different private IPs and different real
IPs.
ISA server Main brach:
NIC1: 192.168.10.240
NIC2: <Real IP#1>
ISA server child branch:
NIC1: 192.168.12.240
NIC2: <Real IP#2>
I have tried to tracert a pc on the main branch but it failed also.
Help needed.
Thanks in advanced.
