A2: yes typically you will use Serial1 as nat outside and E0 as nat inside
A3: If your hosts are on 192.168.111.0/24 then your routers E0 has to get an IP in this network. The config could look like this:
ip address 172.16.101.10 255.255.255.252
ip nat outside
ip address 192.168.111.1 255.255.255.0
ip nat inside
ip nat inside source list 1 interface Serial1 overload
access-list 1 permit any
One more question/remark: 172.16.16.1/27 is not an official IP subnet routed in the internet. In fact none of the IP addresses in your post are official IPs. Did you change the IPs in the post for security reasons? If not, then using NAT on the router might not help you.
How can i able to do this, if my e0 is a private ip?
My previous setup was e0 is a public ip, so my server's gateway is the e0's ip. Since i'm using NAT, e0 would be private. if i use the public ip what gateway i should use? it is not possible to use the s0 ip because its on /30 subnet. my public ip is /27, so the gateway must be on the same block. right? can you give a sample config, on how am i going to do this? Take note i'm using a 2520 router with only 2 serial and 1 ethernet interface and a 2924 switch.
Here is my NAT config its now working..
ip nat inside source list 10 interface Serial1 overload
ok i got it. Thanks, one more question... since i implement this setup. my router seems to restart. and i got an error "System restarted by bus error at PC 0x3500664, address 0x38143269" what does it mean.Are there any draw back with 2 ip in one VLAN.
