Titolo: problema postfix

Salve a tutti ho il seguente problema:
ho una rete così configurata:
un modem router conceptronic cadslr4 con ip dinamico(ma ne ho anche un
altro, un alice gigaset a cui ho cambiato il firmware (ora è un router) e i
risultati delle prove sono sempre gli stessi.. nulla!!!QUINDI FORSE DOVREI
ESCLUDERE IL PROBLEMA ROUTER..) 
Poi ho il mio pc (con suse 9.1 con svariati servizi tra cui postfix) che
prende su una scheda di rete (lato router) la connessione ad internet e
sull'altra scheda di rete ho la lan, dove ci sono alcuni pc con win e
linux. 
Il problema è piuttosto strano!!
in locale all'interno della mia rete casalinga tutto funziona perfettamente
ma nel momento in cui per es un mio amico vuole da casa sua scaricare la
posta dal mio server lo può fare.. nn può invece mandarla perchè (e questo
è veramente strano) "vede", se fa un nmap, la mia porta 25 come chiusa (vi
garantisco che però l'ho aperta, come la 110, ovunque, anche sul router
(che reindirizza i servizi che gli ho detto!!!)).
Sinceramente nn so che pensare perchè la stessa cosa accade al mio amico a
casa sua dove su una macchina con linux sempre con suse 9.1 si è
configurato postfix e ha esattamente lo stesso problema mio.. (lui nn ha
neppure il router per collegarsi su internet.. la sua connessione è infatti
diretta!!)
Penso che il problema debba essere ricercato nel file di configurazione
(
main.cf
)di postfix che nn mi sta abilitando il servizio per l'esterno.. ma
nn ne sono sicuro..
vi riporto la configurazione completa di postfix:

Ciao Andrea

 (che reindirizza i servizi che gli ho detto!!!)).
non e' affatto strano.
Tipicamente gli isp che ti danno l'adsl standard con ip dinamico 
chiudono la porta 25 per evitare che qualche malintenzionato possa
inviare su una macchina pubblica un mini server di posta trojano da
utilizzarsi per inviare spam.

A me, cinque minuti fa, la dava filtered.
E da quello che so, tiscali filtra dal suo lato la porta 25 delle utenze
residenziali.
