[malai.joseph]

Hi, pls help on this

R1921(config)# ip route 192.168.100.0/27 10.10.10.2
R1921(config)# ip route 192.168.111.0/27 10.10.10.2
R1921(config)# ip route 192.168.222.0/27 10.10.10.2
R1921(config)# ip route 0.0.0.0 0.0.0.0 123.49.42.162
R1921(config)# ip nat inside source list 102 int G0/0 overload
R1921(config)# access-list 102 permit ip 192.168.100.0 0.0.0.15 any
R1921(config)# exit
R1921# write

I Want to replace the above with below network kindly help on access list part so as only network  192.168.4.0/26 can browse

R1921(config)# ip route 192.168.2.0/26 10.10.10.2
R1921(config)# ip route 192.168.3.0/26 10.10.10.2
R1921(config)# ip route 192.168.4.0/26 10.10.10.2
R1921(config)# ip route 0.0.0.0 0.0.0.0 123.49.42.162
R1921(config)# ip nat inside source list 102 int G0/0 overload
R1921(config)# access-list 102 permit ip 192.168.4.0 x.x.x.x any
R1921(config)# exit
R1921# write

Hi,

192.168.4.0/26 so subnet mask is 255.255.255.192 and so your wildcard is 0.0.0.63

only network  192.168.4.0/26 can browse

only network 192.168.4.0 will be natted so if you still want external access for the other subnets apart from surfing the web it won't work

Regards.
