dns round robin 其實唔係唔好.. 不過感覺上過唔到自己果關... 又會花network traffic..
Sorry for my late reply as I busy on my work. There is a method below, it use for NAT on a single interface. Just like you want NAT for your internal host ( NAT inside ) and the same interface for outgoing (NAT outside).
======================== interface Ethernet0 ip address 202.123.165.26 255.255.255.128 ip nat outside ! interface Ethernet1 ip address 1.0.0.1 255.255.255.0 ip nat inside ip policy route-map INTERNAL ! interface loopback0 ip address 5.5.5.1 255.255.255.0 ip nat outside ! ip nat pool net-27 202.123.165.27 202.123.165.27 netmask 255.255.255.128 ip nat pool www1 1.0.0.130 1.0.0.131 prefix-length 28 type rotary ip nat inside source list 1 pool net-27 overload ip nat inside destination list 2 pool www1 ip nat inside destination list 3 pool www1 ! ip classless ip route 0.0.0.0 0.0.0.0 202.123.165.25 ip route 202.123.165.27 255.255.255.255 Ethernet1 no ip http server ip pim bidir-enable ! router eigrp 1 network 5.5.5.0 0.0.0.255 network 1.0.0.0 0.0.0.255 ! access-list 1 permit 1.0.0.0 0.0.0.255 access-list 2 permit 202.123.165.27 access-list 3 permit 1.1.1.254 <virtual ip of internal real host> access-list 101 permit ip 1.0.0.0 0.0.0.255 host 1.1.1.254 ! route-map INTERNAL permit 10 match ip address 101 set ip next-hop 5.5.5.2
======================= set ip next-hop 5.5.5.2 use for packet to be route out from loopback interface. you may need to have some modification above to suit you need.
