2821 router can access internet, but I can`t get access to internet on lan

Feredi

Hello cisco community members.

I have a TP- link TD-W9970 modem that is in bridge mode, one 2821 router, Modem lan port & 2821 roter 0/0 port are connected.

modem gateway IP= 192.168.1.1

IP static= 185.120.250.247

router 0.0 IP= 192.168.152.74

router 0.1 IP= 192.168.2.1

pc IP (connected to 0/1 in rouer)= 192.168.2.2

we have one ipsec tunnel that is ok. Router have internet but the pc can`t get acces to the internet.

I`m able to ping router 0/1 port (192.168.2.1) & router 0/0 port (192.168.152.74) & 10.1.1.150 (ipsec tunnel). But I can`t ping the modem gateway (192.168.1.1)

Please help to get access to the internet in pc or switch connected to 0/1 port. I think that I need to a root. thanks for every one that help.

Hello @Feredi ,

in a scenario like yours it is better to use route-maps so that it makes more clear what NAT should do.

 

route-map INTERNET permit 10

match address dsl-access

match interface Dialer 1

 

route-map TUNNEL permit 10

match address POST-NAT

match interface tunnel 4410

 

no ip nat inside source list POST-NAT interface Tunnel4410 overload

no ip nat inside source list dsl-access interface Dialer1 overload

ip nat inside source route-map INTERNET interface Dialer 1 overload

ip nat inside source route-map TUNNEL interface Tunnel4410 overload

 

then also rewrie ACL dsl-access in the following way:

ip access-list extended dsl-access

deny ip 10.0.0.0 0.0.0.255 host 10.1.1.150

permit ip 10.0.0.0 0.0.0.255 any

!

 

Note: the match interface refers to the exit interface in the route-maps.

 

Hope to help

Giuseppe
