Here's the scenario. The company recently upgraded from a 512k ADSL link to a 1M SHDSL link, with all WAN IPs retained. The setup:
Private LAN (10.131.17.x) f/a0 |--- Cisco 1814 ---| WIC-4ESW |--- SpeedTouch ST610s ---| ----->> Internet
1814's WIC: 58.185.xx.193 /28
ST610s Inside: 58.185.xx.194 /28
ST610s WAN: 203.115.xx.78 /30
ISP: 203.115.xx.77 /30
After setting up the ST610s, I connected back everything as it originally was. I then plugged my laptop from 1814's fa0, could ping all the way the ISP's IP (203.115.xx.77) but I just couldn't surf the net (from any other workstations). I tried doing a ping to the ISP's DNS without problems too. Whenever I launch IE, it just shows the page cannot be displayed. I've entered the DNS servers correctly on the ST610s and should I plug my laptop directly to the ST610s, I could surf without problems (therefore, it can't be a virus problem). I'd like to add that I have no access to the 1814. Any ideas?
