Hi.
I'm using nfs root filesystem for developing.
On 2.6.23 everything works fine, but on 2.6.25 loading any iptables
module causes problems:
# modprobe iptable_nat
nf_conntrack version 0.5.0 (1024 buckets, 4096 max)
nfs: RPC call returned error 1
nfs: RPC call returned error 1
nfs: RPC call returned error 1
nfs: RPC call returned error 1
nfs: RPC call returned error 1
nfs: RPC call returned error 1
Probably iptables changed it's default behavior from "allow all" to
"deny all" at startup.
Is there any way to change it back?
I can't change anything after loading any iptable module, because all
programs on filesystem are not accessible after loading...
Regards.

NFS and iptables definitely takes some care - and there are still holes
- no way to specify ports for all requests...
but this seems odd... you must've had some extant rules that suddenly
seemingly changed behaviour before the modprobe was done
