I am running a sun server on a home lan with a Linksys 4 port router model BEFSR41. I have DNS from a DNS service and I have configured the routerin the following manner:
Disabled the WAN block, I am running a static IP which is the same IP I have always had from roadrunner, I disabled dhcp, I enabled the DMZ, I enabled port forwarding using http port 80. I did a ping test to find the best MTU setting and I came up with 1350. I even tried all of the other MTU settings that were suggested by linksys and nothing. A couple of nights ago I had it set to MTU 1492 and it started to work. I could actually see it from outside the lan but the next morning I could no longer pull it up and I have not been able to pull it up since. Very frustrating! I can ping it just fine from outside the lan. I tried pinging the DNS servers from inside the lan and I could only reach one.....don't know if that's a problem. Any ideas, suggestions, answers would be greatly appreciated!
