Hi Okitti,

I don't understand several things:

1. Your network setup -- do you have a network diagram

2. What you want to accomplish

3. What you've done to accomplish your goal

4. What's not working

thanks!
Tom

Dear Tshinder,

internet (203.109.254.100/30)
|

DL320 (203.109.254.101/30)
| |
| |
| |Main office (203.155.95.97/28)
| |
| |
| ISA (203.155.95.100/28}
| | for Main

|Branch Office(goto DL320 Link 2MB) (203.155.95.113/28)
|
|
|
|(203.155.95.120/28)
ISA for Branch
|
|(192.168.1.1/24)

1. Network Rule
Main and Branch NAT External

2. Firewall Rule
Allow All

3. When I use internet for 2-3 Day. Internet is slow on 2 Site (Main and Branch) I will start/stop Service Firewall, So internet always slow but I restart DL320 Internet is ok. I will see any problem on Eventlog and monitor traffic doesn't help me to resolve.

4. When I ping ip on user for branch to Main at 100.1.1.10 (Request time out). I could be ping only DL320 at IP 203.155.95.97.

5. On Dl320 I cannot ping any IP on Gateway ISA for branch

Please Help why doesn't work

Thank you,
