Titolo: 801 e 761... problemi di routing

Ho come l'impressione che mi sto' perdendo in un bicchiere d'acqua (routing
non corretto).
Ho due 761, un 801 ed un router adsl telecom.
Tre sedi:
Centrale:
761                 192.168.10.1    lan        10.0.0.1 wan(remota1)
10.0.0.5 wan (remota2)
adsl telecom    192.168.10.5
Remota1:
761                 192.168.34.250  lan        10.0.0.2 wan
Remota2: (nuova sede)
801                192.168.20.1 lan                10.0.0.6 wan
I due 761 erano configurati tra loro e funzionano perfettamente; i pc nella
sede centrale hanno come default gateway il router 761, il quale provvede a
smistare il traffico verso internet sul router adsl.
E fin qui tutto ok. (La sede remota chiama la sede centrale senza problemi e
viceversa, gli utenti navigano in internet).
Ora, si č ci si č dovuti collegare con un'altra sede che ha un 801.... qui
sorge il problema.
Se dalla sede remota2 eseguo
ping 192.168.10.1 (ethernet router sede centrale)    funziona
se invece
ping 192.168.10.100 (server sede centrale)        non risponde.
Se dalla sede centrale "pingo" il router sede remota2 oppure un client della
sede remota2 tutto funziona regolarmente.
La sede remota1 non ha problemi.
... pensandoci bene, non riesco a capire se il "ping" arriva al server e non
riesce a tornare oppure se proprio il messaggio di "ping" non arriva
proprio.
Dovrebbe, ma non lo č, essere configurato tutto regolarmente, ma mi sfugge
qualcosa.
Molto probabilmente il problema č sull'801.
Ringrazio anticipatamente per suggerimenti.
Allego configurazione router sede centrale e sede remota2 (nuova sede con
801) per maggiori dettagli:
P.S.
Non chiedetemi perchč ci sono due 761 ed un 801 messi cosě... o meglio se
qualcuno ha a che fare con i venditori ne potrebbe sapere qualcosa.

Non ci hai detto tante cose.
1) se fai un ping dal 761 sede centrale verso un client sede 2 va ?
2) I pc sede centrale come hanno il routing ?
3) hai provato un traceroute o tracert ?
4)la configurazione del router Telecom ???
Se i pc della sede centrale hanno solo  default gateway sul router telecom è
li che devi intervenire.
Oppure inserire delle route statiche sui pc sede centrale tipo
route add 192.168.20.0 mask 255.255.255.0 192.168.10.1
In questo caso però i Pc sede 2 non andrebbero su internet
Il problema quindi resta .Dovrai chiamare Telecom perchè se il router
Telecom non riconosce la rete 192.168.20.0 non può mandare i dati che
provengono da Internet sulla rete 2.

 Secondo voi la conf. dell'801 e dell'801 è corretta? Sarebbe inutile
