Don't forget to check a new firewall before you leave the house (Oops...)
Written by on in Vindaloo.


As part of reconfiguring the network yesterday I swapped out the (ancient) router/firewall we've been using as our external firewall and replaced it with the Linksys WRTG (L) we've been using as a wireless-only bridge. (The old router/firewall will go with Rose).

That meant a new internal network configuration, new "virtual server" mappings for the main ssh gateway box (the workstation) and all sorts of other reconfigurations. We spent quite a few minutes yesterday re-configuring applications on the various laptops to work with the new configuration.

But I forgot to test the most important configuration, that virtual-server mapping for the ssh server. And it turns out it's not working today. Sigh. So no email.

Reminds me, need to figure out how to make a host on the internal network "lock" to a given IP address (so that the virtual server mapping remains correct). Old router let you enter a MAC address and assign an IP, haven't found that setting on the Linksys yet.

On the plus side, not having email means I have nothing to distract me from going through tickets and working on them... other than reading news and blogging, that is...

    Yeah, I've done that more than once. Test everything, firewall works, email works, looks good. Then you go back home and try to SSH and and ... nothing. <br />
    I've had it happen when no one there knew enough to fix it, had to wait two weeks before I could access my server :(

    Had something similar on the trip to Albania. Moderately frustrating. This time, it turned out, the Linksys had automatically re-assigned the server a different IP address (why, I can't imagine). Anyway, solution is just to manually assign the IP for the server (on the server) instead of using DHCP, annoying if I ever move the server (for a lan party or whatever), but oh well, it works.<br />

    Glad I didn't have to talk my sister through the process...
