After being using TMG from the past months today it just stopped providing internet to the clients (web proxy)
basic config:
- Interface Internal / External (2 nics) configured as good practice recommends (googled)
- TMG is EDGE
- Windows Server 2008 R2 (currently installing updates for troubleshoot)
- Forefront TMG Std 7.0.9193.575
Symptoms:
- All TMG services started and no notable events in logs.
- connection verifier to the internal dns server is ok.
- connection verifier to external devices (ISP router, ISP dns, http google and pop/smtp mail) timed out.
- ping to loopback is ok
- If i try to ping to the ISP router i get this:
---General failure.
---General failure.

- if i disable the firewall service, internet connectivity returns, so server hardware is ok
the actual config was working until today so i tried to reconfigure the interfaces, rebuild the static routes with no luck, currently im updating server2008 just in case, im running out of ideas... any piece of advice??
thanks
