RouterOS version v3.10
My network looks like this
My fictive public ip: 10.0.0.14/25
My local ip range: 192.168.0.0/24
Internet speed: up: 30 Mbps, down: 30 Mbps.
ISP local speed: 100 Mbps.
Home LAN speed: 100 Mbps.
[home LAN] <-> [RB450] <-> [ISP LAN] <-> [Transperent Mikrotik] <-> [Gateway (Cisco)] <-> [World wide web]
My RB450 act as a NAT to share internet connection to the other computers in my private LAN.
If I upload a file from my home LAN to a computer at the ISP LAN the speed is 8.52 MB/s,
but if I download a file from a computer at the ISP LAN to my computer I get the speed of 100 kB/s
It doesn't matter which Ethernet port at my RB450 I use to act as WAN port, the speed are the same.
The down speed are the same at all computers in my Local Network and at the ISP LAN so there is no problem with some network cards.
This is the NAT
/ip firewall nat
add action=masquerade chain=srcnat comment="" disabled=no out-interface=wan0 src-address=\
192.168.0.0/24
Any clues of why it is behaving like this?
Re: [RB450] Weird througt put with NAT
You did not provide much to go on. The ISP lan is not under your control, correct? It belongs to your service provider? If so, maybe they have a bandwidth control on that server. How is your download speed if not from the ISP lan? Is the internet any better?

yes The ISP is under my control. and there are no bandwidth shaping at the local side in the ISP network.
I have done some investigation about my problem when I do a tracepath from one of the clients of my local network
lets say the gateway of my ISP
anders@Oxynemenus:~$ tracepath 10.0.0.1
1: Oxynemenus.local (192.168.0.98) 0.138ms pmtu 1500

2: 10.0.0.1 (10.0.0.1) 19.993ms reached
Resume: pmtu 1500 hops 2 back 254
As we can see the packages goes in a loop two times in my mikrotik before it goes out to the ISP gatewayackages goes in a loop two times in my mikrotik before it goes out to the ISP gateway. So how come that
