strange NAT issue

[laszlo.pal]

Hi,

I have a very strange issue with my home boxes. I've a brand new Cisco871 router with advance ip services and linux box behind of this router.

I use private subnets on the LAN and router makes NAT for in/out traffic. Incoming traffic NATed by static NAT entries.

Everything works fine except my apache web server. When a client uses http 1.0 protocol everything is fine, but when someone tries with http/1.1 the trasfer timed out. When I check the router and http inspect logs I can see the packets are sent back in this case too, but never arrived to the destination.

have you seen something similar to this?

the same configuration was ok with a linksys broadban router and a linux netfilter based firewall.

Thank you

Laszlo

You know the packets are sent - is that to the 871? Do you know if they leave the 871 - do you have a way of grabbing the packets after they leave the 871?

Can you do a packet capture on the client pc that is somewhere else?

It is looks like the problem was some wrong MTU setting on my linux box... it is strange, but now my site is working again
