Just my observations - it's been my experience that MTU=576 doesn't work with anything, except Windows ME, which ignores this and sets it correctly by itself (and they all still talk bad about ME :-). 95/98/NT/2K/XP all will have problems when MTU is set to 576. It seems a lot of RADIUS servers have this setting by default, but a lot of RAS equipment ignores it, including pre-HiperARC Total Controls, and maybe early firmware ARC's, so the setting had no effect. When a person updates to a newer-style TC, they find users not able to browse because of the MTU setting. - Joel -----Original Message----- From: Moh.

Subject: Re: [USR-TC] HiperARC with WindowsXP Connection Randy and all expert, thanks a lot for your information. We've been set the MTU back to 1500 and Windows XP now can browsing again. My problem is solved. Only I have my own question: why Windows XP can not recieve the MTU 576? -mna- On Thursday 18 December 2003 12:37, Randy Cosby wrote:
Why are you setting the framed-MTU? I'd look there first.

We have an idea to set the system to factory default first and then re-configure again to our setting. Do you have any comment about our planning?

Can you put here any radius authentication packet (access-accept)? You can do it on ARC: monitor radius.
It will look like this one:

get the same

I agree it is strange. I think this has come up on the
list before though.
Check the archives.
That if you are using filters you disble them until you
figure this out.
Actually, we have blocking packet from and to our
customer (at modem
interface site) for TCP and UDP port 135 - 139. It for
blocking virus
-like bluster. Here is the filter: HiPer>> show file filter.135 #filter IP: 010 AND tcp-dst-port >= 135; 020 REJECT tcp-dst-port <= 139; 030 AND udp-dst-port >= 135; 040 REJECT udp-dst-port <= 139; 050 AND tcp-src-port >= 135; 060 REJECT tcp-src-port <= 139; 070 AND udp-src-port >= 135; 080 REJECT udp-src-port <= 139;
Do you think this is the problem? If it true, why it anly
happen at
Windows 32 bit (like Windows XP)? and not at Windows 9x?
When I have a problerm I try to get to the base level, get
it working,
then add stuff back in one at a time. Exactly what
attributes are you
replying from radius with?
