Hello. Thanks developers for cool product. I have a few questions:

1. Could you explain why mikrotik's interfaces are not change their MAC automatically? When I add new node I need manually reset every interface via winbox.

2. When I add 2 or more iol_L2 switches, between 2 other nodes (win xp and linux with apache web server, for example) I can't open web-server start page via browser on win xp. But pings, telnet, fttp are going. I have tried some images of iol. On one browser endlessly downloaded the page, on another displayed timeout error. Is it bug?

Thanks

1. It could be wrong image compilation. Sometimes when ppl create images they save static setting on default image. So it is not a EVE bug but Mikrotik compilation issue.
Auto change of MAC obviously works, if image is OK.

2. IOL IRON L2 image has bug for L3 transfer, so ip cef needs to turn off. no ip cef. But such behavioure that you can reach other end with ping or TFTP, but not http is not obeserveed. Chech that ip cef issue.

Uldis, thanks for answers. Unfortunately, disabling ip cef doesn't solve the problem. Same problem with vIOS. I can ping, telnet and fttp (even telnet to 80 port on one img), but cannot http. Wireshark shows problem with tcp (spurious transmission end "connection reset" flags).

Any ideas?

Excuse me sir, but it looks like you doing something wrong..
here is your task done on EVE, used IOL switches IRON and trunk between them.
Used win7 and Ubuntu server at another end. As you can see I can ping from win7 to ubuntu and have web access without any issues.

central SW5 has DHCP pools for win7 VLAN 11 and Ubuntu VLAN 12.

Works perfect..

ONLY one thing I can recall if some Antivirus doing deep virtualization inspection, maye for that it doesnt work for you

Oh, interesting... Howbeit, I have known it should work fine
By the way, even if I add not configured sw's and nodes in the same net on the ends, "http-problem" is still there. I have no any antivirus on node with winxp and have just win10-embedded av on my host with wmvare. Linux-node's browser can't reach start page or mikrotik web-gui too.
One week before I had caught 2 blackouts with working lab. After that I lost any connections between nodes in my lab(despite of all was working fine and configs was saved before). I rebuilt (made new) lab and all (look like) was working fine before I find "http-problem"

May it(blackouts) be the reason of my problem? Should I reinstall eve-ng?
I didn't find information about vmware tools. Should I install it?

I reinstall eve accroding to "how to".
The problem saves . But your topology is working in my lab too. Could you try this topology (below)

All switches work on lyer 2 (without routing features). Routing is configured on router

Just replicated same lab:)

Works like charm !!!!
Use router IOL 15.4.2T, dot1q interface for vlan 10,20...look lab
switch IOL IRON L2 15.2, switches are L2 only trunks/access ports and vlans on them
win7 host DHCp client, got IP from router pool 192.168.10.2, ping to mikrotik 192.168.20.2...perfect
Mikrotik stat IP eth1 192.168.20.2, ping to win host to 192.168.10.2 ..perfect

I am gonna close this topic:)

In my case ping goes to! And telnet! And ftp! But, suddenly, not http! I have broken my head! I just made:
sw trunk encapsulation dot1q
sw trunk allowed vlan 2,3
sw mode trunk
+
sw mode access
sw acc vlan 2 or 3 (had made vlan 2 and 3 before)

Thats all on switches!
Router
sub interfaces + encapsulation dot1q and static addresses. Nothing else!
If I had came to web GUI mikrotik before made trunk (all switches without any configs, just static ip to the ends (win or linux and mikrotik or linux apache)) I can do it again after making intervlan routing. But if I clear cash in the browser... I am not able to come on mikrotik again... I am just overwhelmed. I can't sleep and eat
Do you recommend to install wmware tools?
