Cisco 837 problems

[directlyconnected]

I have problems with certain web sites (usbank.com to name one) that will not load all the way, where others like this one and Yahoo mail open and perform other functions just fine. I run Windows XP Pro, Firefox (IE does the same thing on the same sites). Any tips? here's a config...

I don't think it's because I have "x"'s for the ip addresses and "*"'s for passwords...

Hi,

I think the problem might be linked to MTU and ICMP blocking of various webservers which will not allow the ICMP message to be sent back to your router telling it to shrink the packet size. PPPoE is often subject to this problem. see this:

http://www.cisco.com/warp/public/794/router_mtu.html

hope this helps...

You are a genius. I did think the mtu size had something to do with it, but I tried making it higher (whoops), and I did not think about servers blocking icmp. But you did, and I thank you once again. I did as the article instructed, and viola! Thank you. Do you have a Cisco adsl router?

No worries. Purely by chance i was researching that MTU problem last night for a VPN issue.

I have a Cisco 837 ADSL for home use, it's PPPoA though so no similar problems with MTU.

What version IOS? Also, do you have a need for version 12.4 for a 1720? maybe we could trade?
