Hi there,
I have a C871 in place. Everything is working great except that Microsoft websites won't load on client computers. IE finds the site and just sits there loading forever. I have tried a other sites and they all work perfectly.
I am really stumped because I can't see any difference between Microsoft site traffic and any other site.
Any ideas?
Best...Andy
MTU?
If so you could try
int vlan 1 ! --> or whatever your inside one is ip tcp adjust-mss 1300 !--> I see no point in worrying about 100 bytes.
I have an MTU issue that has appeared suddenly on an 877. I have no idea what is going on but the above has fixed it for me.
Thanks guys. The ip tcp adjust-mss command was my friend. I configured it to
1400 and it just runs smooth now.Best...Andy

This is of course not the "correct" solution. Ideally path MTU discovery should be working:)
Your outside interface should be permitted to issue and respond to the relevant ICMP packets.
! I don't object to ping 10 permit icmp any any echo-reply (125 matches) ! or traceroute 20 permit icmp any any time-exceeded (72 matches) ! permit path MTU discovery 30 permit icmp any any unreachable (24 matches)
