Router and iBurst

[BadBoyZ]

Yes, IE just keeps waiting for a reply.
I can't find a MTU setting under the router setup, beginning to think I need to kick it down the street and find myself a new one.
I tried the mtu ping test but I'm able to go all the way to 1400 (without the added header bytes) before fragmentation starts.

Thanks for your help thus far, any other ideas?

Mtu

Ditto - start with the lowest and see if you can connect and then fiddle with the tweaking tests ...

MTU 1392

 

[MrH]

For now set it at 1372.

In IE make sure under Connection Lan Settings that Proxy Server is UNticked, besides that setting it should work.

Or try FireFox and also make sure no proxy is selected.

 

[GuRu]

Sorry mean't MTU 1352 If you bypass the router and plug straight in does it work then ?

 

[MrH]

Guru I guess you should be able to help as I'm sorta running out of ideas here

 

[GuRu]

The Dynamic DNS should be ticked on the router , on my Dlink i have the option ticked.

 

[MrH]

Try rebooting after changing that setting

 

[MrH]

On my router it is Disabled

The Dynamic DNS should be ticked on the router , on my Dlink i have the option ticked.

This is for the WAN settings ..

 

[MrH]

I missed that post about you not been able to obtain IP automatically, maybe thats something to do with SP2, I still have SP1

Maybe Guru can help you with SP2 settings.

 

[MrH]

rgr Guru there I also have it ticked

It may help if you set the MTU reasonable (1352) on your windows machine's ethernet card. That's what I did initially to get past IPCop's larger MTU.
Since I have about 8 entries in the registry, I used DrTCP to set it.
At the moment I have IPCop set to 1432, left the Linux box at its defaults and have Windoze at 1424. Seems to work fine.

 

[MrH]

I need to logoff for awhile, but I'm sure between Guru and jmn it will be sorted out.

Will check back later to see if you get it working.

The other thing to try is to disable all firewall and antivirus and see if that helps. If it does then re-enable one by one checking to see which one causes the problem.
I also am running XP +SP2 but with firewall turned off, i use the router firewall.

BadBoyZ from what I've read in this thread your problem seem to me to be MTU size.

Firstly dont mess with Win ... leave on defaults ... you must set it on the router.

Unfortunately I have a D-Link so I dont know where it is on the MSI, however on most routers its usually in the WAN section close to where you set PPPoE username & password. The default is probably 1500 so if you see this value change to 1352.

BTW the limited or no connectivity message when you connect PC directly to UTD can be easily solved by going to the physical connection in Win (either USB or Ethernet) and disabling (un-ticking) TCP/IP on it.

Hope this helps.

Hey, sorry I'm only replying now. Wasn't near my pc for a while.

I managed to get it to work ... for a very short while
Now before you start laughing let me explain.

I modified my router settings and turned off the firewall but as before IE still got no response. So I went to the policies section and specified "pass" for all http wan-to-lan packets and amazingly it worked! So I decided to turn the firewall back on but this caused IE to stop functioning and just wait for a reply as before. No problem, I'll just disable the firewall again but for some reason this didn't work. So I freaked out and removed and readded the policy but it didn't help. Since then I've tried everything to get it to work again (restart router, use factory default settings, redo policy with firewall off/on) but it doesn't want to. I even resorted to banging on the router ... ermm ... with my head ... numerous times, didn't help.

At least we know it isn't MTU as I couldn't find a function to change it on the router and as such I just didn't.

Thanx for your help thus far, I think it's clear the firewall is blocking the responses but I can't stop it! Here are the settings I can change on the Firewall:

Firewall: High/Low/Disabled (disabled doesn't seem to do much)
Wan-To-Lan: Pass/Deny (obviously on Pass)
Lan-To-Wan: Pass/Deny (ditto)
ICMP Error Messages: Pass/Deny (tried both)
ICMP Blocking: Enabled/Disabled (tried both)

I can also create policies (pass all http to ip for example) and create a DMZ server (which didn't help).

Again, thanx for all the help, something like 30 replies are quite a lot!

I'm outa ideas as I never had any of the problems that you seem to be having.

You do have the winXP firewall turned OFF right?

If so then since the router seems to be working we will have to wait for the SP2 experts to reply.

As a matter of interrest I have the router firewall ON as well as running Zone Alarm, but I only left ZA activated to see if it was still blocking any attacks, until now 0 blocks as the router firewall is working well.

I will most probably remove ZA in a short while as all it's doing is wasting ram.

BadBoyZ still think your going to run into trouble if you arent able to set mtu below about 1432 ... unless the router autosenses it (dont think so).

Try to upgrade firmware on the MSI to latest ... maybe newer versions have mtu setting.
