Telling the router to do destination nat is one thing, allowing that packet through the firewall is different. So if you have: chain=dstnat action=dst-nat to-addresses=192.168.1.15 to-ports=9090 protocol=tcp dst-address-type="" src-port=9090 dst-port=9090 log=no log-prefix="" then in /ip firewall fi...

I suspect you have a split routing or MTU issue as there are a lot of people using ipsec over pppoe without issue. I have one box plugged into 1000/100 pppoe internet connection and it's doing a lot of VPN work for an office of engineers.

If I use /fetch into a directory, the system does't create that directory, instead it creates it as a file: [admin@hotspot104] /file> /tool fetch user=hotspot password="xxxxxxxxxx" url="https://domain.net/Hotspot/Files/hotspot104/login.html" dst-path=hotspot/ status: finished downloaded: 0KiBC-z pau...

I would like to track sessions and use normal /ip firewall filter rules for src addresses in list1, list2, and list3, but for everything else I don't have any need to track connections. Can I accomplish this with? /ip firewall raw add action=return chain=prerouting src-address-list=list1 add action=...

No, you can not do this. Authentication without whole PKI chain including root CA is not possible. Perhaps what we could do is add possibility to match an Identity based on a specific common field in client's certificate, for example, Unit. You could generate multiple client certificates with the s...

Right now we have three ways to authenticate certs in ike2: match-by=remote-id remote-id=user-fqdn:user@domain.com or equivalent or match-by=remote=id remote-certificate=<cert> or match-by=certificate The first two require us to identify every certificate that can be used to authenticate. The last o...

If we had: name="rw-config" system-dns=yes address-pool=roadwarriorips address-prefix-length=32 responder=yes dst-address-list=roadwarriors Then in the firewall we could reference the roadwarriors list and create dynamic firewalls for anyone connecting with the above mode-config. This would be vastl...

There is nothing to be "fixed", it works as expected. The trust chain is from the endpoint certificate up to the root CA and it cannot be shortened arbitrarily. Plus to work, the entity checking the validity of an endpoint certificate must have access to the complete chain of CAs, while the one of ...

I have a certificate authority and a sub CA then my server and road warrior cert. Like this: ROOT CA | VPN CA | | Client cert Server cert The idea is that I only want client certs signed by the VPN CA to authenticate, not every user cert signed by ROOT CA. I thought I could do this by simply putting...

This is what I need, a way to make a firewall list based on ipsec identity. All that's needed to make this work is the ability to define src-address-list when responder=yes: /ip ipsec mode-config add address-pool=ike2-pool address-prefix-length=32 name=ike2-firewallrulesA src-address-list=firewallru...

I would like to build a chain of firewall rules, then assign that chain to road-warrior VPN clients that authenticate with ike2 and thus are identified by the ipsec identity, and thus the ipsec mode-config. What would be great is if the src-address-list attribute on ipsec mode-config worked in respo...

RouterOS Devs: The default user creation doesn't require a password, and defaults to blank, which means if someone simply does a: /user add name=fred group=full Then you can immediately login as fred with no password.

There are plenty of limitations for service providers as well. 1. BGP is single core. 2. VRF's pretty much don't work because local connected routes are always available to all tables. 3. SNMP monitoring support is terrible. 4. openvpn only works in TCP mode. 5. Limited -48v DC options (though this ...

The routeros platform is pretty limited in regards to monitoring with snmp. If I want something like cpu resource monitoring or ipsec SA monitoring, then I have to find other ways to monitor than snmp. However, there is a super simple way that mikrotik could fix this: Assign an OID to each /system s...

Thanks for the response. You are right, they are invalid packets, because the tcp timeout on connection tracking is super aggressive. I relaxed that a bit and that helped, now I'm dropping invalid traffic before it hits my logs so that I'm not filling up my firewall logs with tcp timeout nonsense. A...

More oddness: If I trace a flow using logging in the prerouting or post routing chain I see something like this: Where 1.1.1.1 is the public client, 2.2.2.2 is the public facing address on the routeros host, and 3.3.3.3 is the private address I'm doing port address translation to: Mar 30 12:26:32 pr...

As someone that runs 4000+ pppoe sessions on x86 routeros I doubt that the CCR1036-12G-4S could do it. The pppoe server code doesn't thread well (at least on x86) and other posts on the forum seem to indicate you will have one CPU absolutely at 100% while the remaining 35 cpus idle. As far as mikro...

I'm seeing this too. And it's hard to figure out where the traffic is coming from because the routeros sniffer either doesn't work right or it's lying to me because it shows the traffic on bond1 when interface is any: 1 0.035 bond1 129.0.0.71:49320 ...

It doesn't look like the builds are being updated. I just downloaded the latest and it says the build time was Apr/13/2015 14:10:30.

I really hope the ssl bug gets fixed, it's making pulling config from https impossible.

I was told by support that the fetch/ssl bug (http://forum.mikrotik.com/viewtopic.php?f=1&t=95576) would be fixed in the next release, but the latest version (version: 6.28, build-time: Apr/13/2015 14:10:30) still doesn't download more than 4096 bytes.
