So I finally got around to building a big x86 based system. And a beauty she is too…
The important things are the three ethernet cards and the Level 5 licence.
The problem is that something’s wrong.
The machine’s running RouterOS ver 4.3 for x86 and the version of user manager that was shipped with ver 4.3 of RouterOS.
One ethernet (E1) port goes to the rest of the network.
One ethernet (E2) port goes to a Cisco router an on to a fibre optic connection to an upstream service provider.
The last ethernet (E3) port goes to a Linksys ADSl router in bridge mode for specific local only traffic.
I have source NAT set up so that all traffic leaving on E2 is NATted and all traffic leaving on E3 is natted.
E2 has a static IP address supplied by the service provider
E3 has a PPPOE connection and gets a dynamic IP address.
There are some sites that I simply can’t browse.
If I go (for example) to http://forum.landerovernet.com I get the following error:
The connection was reset
The connection to the server was reset while the page was loading.
- The site could be temporarily unavailable or too busy. Try again in a few
moments.- If you are unable to load any pages, check your computer’s network
connection.- If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.
IE gives:
Internet Explorer cannot display the webpage
