Ngaphansi kweminyaka eyi-10 kamuva, abathuthukisi be-RoS (ku-6.47 ezinzile) bangeze ukusebenza okukuvumela ukuthi uqondise kabusha imibuzo ye-DNS ngokuya ngemithetho ekhethekile. Uma ngaphambili bekudingeka ukuvika ngemithetho ye-Layer-7 ku-firewall, manje lokhu kwenziwa kalula nangobuhle:
/ip dns static
add forward-to=192.168.88.3 regexp=".*\.test1\.localdomain" type=FWD
add forward-to=192.168.88.56 regexp=".*\.test2\.localdomain" type=FWD
Injabulo yami ayinamkhawulo!
Lokhu kusisongela ngani?
Okungenani, sisusa izinto eziyinqaba ze-NAT ezinjengalezi:
/ip firewall layer7-protocol
add comment="DNS Nat contoso.com" name=contoso.com regexp="\x07contoso\x03com"
/ip firewall mangle
add action=mark-packet chain=prerouting comment="mark dns contoso.com" dst-address-type=local dst-port=53 in-interface-list=DNSMASQ layer7-protocol=contoso.com new-packet-mark=dns-contoso.com passthrough=yes protocol=udp
add action=mark-packet chain=prerouting comment="mark dns contoso.com" dst-address-type=local dst-port=53 in-interface-list=DNSMASQ layer7-protocol=contoso.com new-packet-mark=dns-contoso.com passthrough=yes protocol=tcp
/ip firewall nat
add action=dst-nat chain=dstnat comment="DST-NAT dns contoso.com" dst-port=53 in-interface-list=DNSMASQ packet-mark=dns-contoso.com protocol=udp to-addresses=192.0.2.15
add action=dst-nat chain=dstnat comment="DST-NAT dns contoso.com" dst-port=53 in-interface-list=DNSMASQ packet-mark=dns-contoso.com protocol=tcp to-addresses=192.0.2.15
add action=masquerade chain=srcnat comment="mask dns contoso.com" dst-port=53 packet-mark=dns-contoso.com protocol=udp
add action=masquerade chain=srcnat comment="mask dns contoso.com" dst-port=53 packet-mark=dns-contoso.com protocol=tcp
Futhi akugcini lapho, manje ungabhalisa abadluliseli abambalwa, okuzosiza ukwenza i-dns failover.
Ukucubungula kwe-DNS okuhlakaniphile kuzokwenza kube nokwenzeka ukuqala ukwethula i-ipv6 kunethiwekhi yenkampani. Ngaphambi kwalokho, angikwenzanga lokhu, isizathu siwukuthi ngangidinga ukuxazulula inombolo yamagama e-dns kumakheli endawo, futhi ku-ipv6 lokhu kwakungeke kwenziwe ngaphandle kwezinduku ezinkulu.
