>13MB netfilter forward CRASH

[Kevin Quinn]

Greetings.  I am not subscribed to the list yet, so please respond to my 
email address.  if this get's hairier, I'll get on the list.

I am having the exact same issue Marcel de Boer posted about last month. 
  I have a WiFi and ethernet network in the house.  traffic from them is 
forwarded along by a central linux box (redhat9) that also is connected 
to the internet via a cable modem.  I am running NAT internally to run 
off the one ip address my ISP provides.  I do plenty of filtering on the 
internet interface, but forward along anything from the inside.

I have transferred files via FTP from the internet to the linux box as 
large as 6GB.  when I try to FTP from a machine behind the linux box, 
the transfer goes fine until ~13MB then the linux box HANGS!

I do get some messages, but they happen periodically earlier in the 
transfer as well.

kernel: skb_p80211_to_ether: OTHER frame too large (1536 > 1500)
kernel: skb_p80211_to_ether: DIXII frame too large (1528 > 1500)


the same has happened from multiple boxen.  any lowly windoze box I can 
find can bring my linux box to an absolute halt.  ouch.

if it would help, I can test this with no iptables rules, but I can't 
imagine a different result.

so, did Marcel find the answer or maybe someone has other clues?
