I have a Netgear WNDR3700 router that I use in my domestic lan; previously I used a router Cisco 827 for my lan, and now I use 827 for the ADSL connection (my provider use PPPoA protocol). The Netgear is introduced to Cisco (with 192.168.1.1 address) with 192.168.1.10 address and work correctly; Now I ask : is it possible to open all ports in 827 (filter is on the Netgear) ? is it possible make a configuration in order to route all traffic from ADSL to the Netgear (827 make function of pure ADSL Modem) ?
This is my actual 827 configuration :
version 12.2 no service pad service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname yyyyyyyy ! enable secret 5 xxxxxxxxxxxxxxxxxxxxxxxxx. ! username yyyyyyyy privilege 15 secret 5 xxxxxxxxxxxxxxxxxxxxxxxxx mmi polling-interval 60 no mmi auto-configure no mmi pvc mmi snmp-timeout 180 ip subnet-zero ! no ip dhcp conflict logging ip dhcp excluded-address 192.168.1.1 ! ip dhcp pool LOCAL network 192.168.1.0 255.255.255.0 default-router 192.168.1.1 domain-name zzzzzz dns-server 18.104.22.168 22.214.171.124 126.96.36.199 188.8.131.52 lease infinite ! interface Ethernet0 ip address 192.168.1.1 255.255.255.0 ip nat inside hold-queue 100 out ! interface ATM0 no ip address no atm ilmi-keepalive pvc 8/35 encapsulation aal5mux ppp dialer dialer pool-member 1 ! dsl operating-mode auto ! interface Dialer0 ip address negotiated ip nat outside encapsulation ppp dialer pool 1 ppp chap hostname xxxxxxxxxxxxxxxxxxxxxx ppp chap password 0 xxxxxxxxxxxxxxxxxxxxxx ppp pap sent-username xxxxxxxxxxxxxxxxxxxxxx password 0 xxxxxxxxxxxxxxxxxxxxxx ! ! ip nat inside source list 1 interface Dialer0 overload ip nat inside source static tcp 192.168.1.10 4662 interface Dialer0 4662 ip nat inside source static udp 192.168.1.10 4672 interface Dialer0 4672 ! ip classless ip route 0.0.0.0 0.0.0.0 Dialer0 ip pim bidir-enable ! ip nat inside source static esp 192.168.1.10 interface Dialer0 ! access-list 1 permit 192.168.1.0 0.0.0.255 ! call rsvp-sync ! voice-port 1 ! voice-port 2 ! voice-port 3 ! voice-port 4 ! ! line con 0 stopbits 1 line vty 0 4 exec-timeout 120 0 password xxxxxxxxxxxxxxxxxxxxxx login local length 0 ! scheduler max-task-time 5000 end
if the provider uses PPPoA service you cannot set the 827 as a bridge. if it were PPPoE over ATM you could do that.
About filtering ports I don't see any ACL on your 827 configuration but I guess you are referring to TCP ports and NAT.
the 827 needs to know the IP subnets behind the other device with static routes for example and to perform NAT for those IP subnets in addition to net 192.168.1.0/24 OR the other box has to do NAT too.
