Troubles to connect via LAN to "the Dude"

RouterOS The Dude
1

Hi,

Here I am:

Dude running onto a Suse server.
Every thing is okay : I can connect with a client CPU when I’m plugged directly to the switch right to the server.

So it means . Dude looks correctly intalled and I got no trouble / firewall 'settings.

But :

I’ve tried to establish a remote connection.
Same LAN , only one wireless point to point (max bandwidth = 6Mo/sec…) is separating me from the dude’s server:

C:\Users\UTILISATEUR>tracert 192.168.0.8
Détermination de l’itinéraire vers 192.168.0.8 << my dude’s server
avec un maximum de 30 sauts :
1 <1 ms <1 ms <1 ms http://www.mydudeserver.com [192.168.0.8]

tracert ok
So I “Wiresharked” my dude server to go forward to find the reason why:

I 've got some Checksum error, some bad tcp anaylis flags…

here is a copy of my problematic sniffed packet :

_TCP. src port 2210 , distant port 63835 …ack sequence n° …

Checksum : 0a472 [incorrect, should be 0993a (maybe caused by checksum offloadind?)]_

Now I need some help :/, coz I really need some remote access.
I m already using many mikrotic’s routers…got lot of devices to secure and to manage…
Thx alot for some help :slight_smile:
I could give you my skype Id …

Hi … It 's me … Again ^_^.

I think I have a part of the clue. But need ur help:

When The link is starting betwen my CPU & dude’s server, the connection is starting onto :2210.
primary connections are established. I can see some UL and DL onto my remote client… but the it stop.

Because I noticed this with wireshark:
Then The dude 's server is answering to my CPU:
BUT : The port it’s using to answer is never the same… 63606,60478..etc etc =)
So i suppose it got to be important to open a specific port onto my router between me and the dude server), to be able to let that answer pass throught it. ( settings on the router are the default ones.)

I had a look in settings, but I cant find a way to block that answer onto one specific port. e.g: 60470.

( I can precise I’m using the dude v2.0) on both CPU, because I had some troubles / with the other version… )



Thx for support.

Best regards.
