Hi,
I have a cisco 857 with nat for the intern net 192.168.0.0/16
ip nat inside source list 100 interface Dialer0 overload
access-list 100 permit ip 192.168.0.0 0.0.255.255 any
I have a full redirection to a ip intern: (It's a little strange maybe ?)
ip nat inside source static 192.168.45.1 interface Dialer0
And i will acces to snmp for the router and for the other device
ip nat inside source static udp 192.168.45.1 161 interface Dialer0 163
ip nat inside source static udp 192.168.45.2 161 interface Dialer0 161
Now i have a problem if i do a ping to a public ip from the router:
ping x1.x2.x3.x4 source 192.168.45.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to x1.x2.x3.x4, timeout is 2 seconds:
Packet sent with a source address of 192.168.45.2
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 60/60/64 ms
ping x1.x2.x3.x4
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to x1.x2.x3.x4, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
In the second case all the trafic is forwarded to the intern device:
18:30:08.410328 IP x1.x2.x3.x4 > 192.168.45.1: ICMP echo reply, id 7, seq 0, length 80
So how can i solve this ? How is the way to do something like what ?
Regards
