Salve,
sono nuovo del forum e vi saluto tutti. Vorrei chiedervi aiuto su una situazione che non riesco a risolvere.

Rete:
ROUTER (78.x.x.x wan e 192.168.1.1 vlan) - RETE LAN 1 (192.168.1.x) - ROUTER CISCO (192.168.1.3 wan e 192.168.10.1 vlan) - RETE LAN 2 (192.168.10.x)

Caratteristiche:
- tutte le due reti hanno netmask 255.255.255.0
- il router 192.168.1.1 a cui non ho accesso natta 1:1 l'ip pubblico su 192.168.1.3 (router cisco)
- il router cisco è un vecchio 851 con IOS c850-advsecurityk9-mz.124-9.T7.bin
- il router cisco gestisce 2 PPTP, una come client "vpdn-group 1" (per accedere ai due server 192.168.2.10 e 192.168.254.10) all'atro capo della VPN e una come server "vpdn-group 2" ai cui client assegna il pool 192.168.10.200 - 192.168.10.205.

Problemi:
- entrando in PPTP da fuori la rete sul router cisco, l'accesso va a buon fine, mi viene assegnato l'ip 192.168.10.200, riesco a pingare 192.168.10.1 ma non il resto della RETE LAN 2 (192.168.10.x) e neanche la RETE LAN 1 (192.168.1.x)
- ho provato a fare un nat con "ip nat inside source static tcp 192.168.1.2 22 interface FastEthernet4 22" ma alla connessione SSH non riesco a raggiungere l'host indicato.

Come sicuramente potete capire ho poca conoscenza di configurazione cisco, sono poche settimane che ci provo da autoditatta. Spero possiate darmi una mano a risolvere il problema.

Grazie.
