you know, I did this. flushed the table, took the system down to runlevel 1
and then flushed again and then brought the system back upto runlevel 5

(yeah...a _Tad_ overkill but anyway)

so i double and triple checked the masquerade rule, recompiled the
kernel and put in advanced router and took out ip aliasing (shouldnt
that be marked as 'depreciated' ;), re-checked the route table 
(route -N) and it all still looked the same.

_TheN_ 

i took out the modules iptable_mangle and iptable_filter (Which were 
being loaded for who knows what) and *ahem* it now works and 
masq's all the outgoing/incoming packets fine.

so smack me with a fish and colour me stupid, but it seems 'fixed'.

but.....
Can anyone though please explain _Why_ this is the case ?
