MahmoudSaber -> Clients via FWC are not able to use ICMP or microsft-ds Plz help (10.Aug.2011 4:28:25 PM)

I Have a scenario
where i have ISA server connected to the Internet
and 3 switches each represent a separated network

I have a DHCP
a Domain controller
and a Router with 3 interfaces each in a network

My router also acts as DHCP Relay agent

PCS in Network 1...............
IP 10.10.1.x
Mask 255.255.255.0
GW 10.10.1.4

PCS in Network 2...............
IP 10.10.2.x
MASK 255.255.255.0
GW 10.10.2.4

PCS in Network 3...............
IP 10.10.3.x
MASK 255.255.255.0
GW 10.10.3.4

Router interfaces..........
10.10.1.4 , 10.10.2.4 , 10.10.3.4
All Masks 255.255.255.0
no GW


ISA Server LAn Card.......
10.10.1.254
255.255.255.0
10.10.1.4

ISA Server Wan Card
Real IP





My Question is:

I use firewall client on all PCS in the 3 Networks
but I cant ping external IPs (Internet or VPN IPs) ...............................1
also I cant browse any PC in the vpn network " Network in the branch Site " ......2
browse = accesing port 445 on remote PC by \\192.168.0.x

This is not the real scenario but i tried to simplify everything as possible as ican
Please tell me how to solve these 2 problems
