As far as a I know: - DNAT can be made with PREROUTING - SNAT can be made with POSTROUTING NAT makes DNAT to change the target of a packet, and makes SNAT to change the source of a packet, so I conclude: - PREROUTING is for incoming traffic - POSTROUTING is for outcoming traffic Is it PREROUTING: This chain is used to make any routing related decisions before (PRE) sending any packets. Prerouting Prerouting adalah proses pendefinisian packet yang akan masuk ke dalam tubuh router melalui interface. There is no mangle opportunity after that to re The difference between mangling in forward and in postrouting is that forward only handles transit packets, i. Postrouting (Mangle) see every forwarded packet, Output (Mangle) sees only the packets generated by the router self and in this case your outgoing encrypted traffic.

Community discussions. g. To set MSS you have to use Postrouting as then the outgoing packet is still unencrypted. The packet that forward passthrough the router will match prerouting first. You can even sniff the same packet multiple times (once in prerouting, once in postrouting) and send them to different ports (so you can have multiple Also the 'MTCNA' of MikroTik Canada was helpful. Makes sense! add action=mark-packet chain=postrouting connection-mark=STEAM \ new-packet-mark=STEAM passthrough=no As you can see, I have marked the connection in prerouting, and then marked packets in prerouting and postrouting, using the same connection markup, and marking the same package name in pre and postrouting. router's own DNS queries, downloads etc. hello sir we are using mikrotik router for our bandwidth limitation we found an option that is prerouting and postrouting we searched in google but the result it gives is unsatisfied by us so can you explain clearly. A packet can only have one mark at a time, but can I change the mark for example, give it a mark in prerouting, then change it in Forward and finally change it again in postrouting? 3. 2/24 interface=WAN3 /ip firewall mangle add action=accept chain=prerouting disabled=no dst When you have only a single rule like that, there probably is not much difference.

As the routing descision is only made between prerouting and forward, therefore in prerouting mangle, I cannot use my natted LAN IPs as dest-addr or dst-addr-list, nor my LAN interface as out-interface, only in forward-mangle and postrouting-mangle. There are seven types of Chains in Mikrotik. Code: Select all /ip firewall mangle add action=mark-connection chain= prerouting new Also the 'MTCNA' of MikroTik Canada was helpful. The packet flow is prerouting mangle, prerouting filter, destination NAT, global-in/global-total. Edit space details. The do pass the output and postrouting chain, but that is after the 'routing decision', hence of no use. At that point, the queues can consult a packet mark. If I follow the packet flow I indeed now understand that packets originating from the router will not pass the prerouting chain. But prerouting 35655 packets is far more than input + forward (8 855 + 18 497 =) What I need is for the packet to exit the prerouting/forward chain as soon as it hits a particuar rule. 9. artinya adalah marking koneksi awal dari jaringan local menuju internet akan masuk ke router melalui interface local,biasanya digunakan pada mark connection. Makes sense! Also the 'MTCNA' of MikroTik Canada was helpful. General ISP and network discussion also permitted. Input, Output, forward, prerouting, postrouting, srcnat, dstnat. hello sir we are using mikrotik router for our bandwidth limitation we found an option What differences are there in where you mark? What would you want to mark in each chain and why? Suppose I was trying to use a simple queue or queue tree, should I mark Mangle is a kind of 'marker' that marks packets for future processing with special marks.

The optimization would be to look at packets and mark the corresponding connections in prerouting, and in postrouting or other place MikroTik. this connection will be in the process inside the router, can the process of bending to the external proxy, can filtering port, can postrouting 92 129 packets is quite close to forward+ output (18 497 + 73 511 = ) 92008 packets, with only 1. But then you still can't use ipsec-out because it is still before that is set. those the router forwards from one interface to another, whereas postrouting handles both forwarded packets and packets sent by the router itself (i. 123.

Pada menu Firewall → Mangle terdapat 4 macam pilihan untuk chain, yaitu Forward, Input, Output, Prerouting, dan Postrouting. I'm definitely not an expert on Mikrotik's queueing, so I could be wrong here, but that's my take. The PREROUTING chain: Rules in this chain apply to packets as they just arrive on the network interface. Makes sense!

I have a queue tree on two interfaces (in / out) with 12 queues on each interface, and a firewall setup with packet tagging on the mangle chain (34 items). Kupas Tuntas Apa itu Prerouting, Postrouting, Input, Output. Register An what these so called prerouting and postrouting operations do than "normal" routing operations don't do already? Thank you From my experience those are Mikrotik specific terms. Makes sense! MikroTik Community discussions vs mangle. Always remember that in PREROUTING/POSTROUTING i. So if I do (in prerouting) tcp, dst 3724, action=accept the packet will leave the chain immediately and not pass through other rules in the prerouting chain, thus minimizing the delay while the packet traverses the whole chain. The possible flows are as follows in mangle: prerouting -> input prerouting -> forward -> postrouting output -> postrouting Note that using postrouting will cause forwarded traffic (the vast majority of your traffic) to follow both chains Also the 'MTCNA' of MikroTik Canada was helpful. Destination NAT isn't only used for port forwarding, it is also where source NAT is As the routing descision is only made between prerouting and forward, therefore in prerouting mangle, I cannot use my natted LAN IPs as dest-addr or dst-addr-list, nor my LAN interface as out-interface, only in forward-mangle and postrouting-mangle. This would make each packet except the first one of each connection pass only a single rule in that chain rather than all three. Makes sense!

From my first link:-----What we are interested are the nat table and its builtin chains PREROUTING, OUTPUT and POSTROUTING; and the mangle table and its builtin chains, PREROUTING and OUTPUT. Thanks for the hints. Also the 'MTCNA' of MikroTik Canada was helpful. 1. There are five types of chains, srcnat and dstnat are subsets of other chains, but for a better understanding, we consider these types separately. Community discussions I'm trying to setup mangle rules to create load balancing but I'm battling to decide between using prerouting and input chain. Routing rules don't accept address lists and generally provide very few parameters for traffic filtering.
