I want to make GRE tunnel between Cisco and mikrotik. On mikrotik i have 2 ISP. I make PCC load balancing and it works just fine. when i take a look in IP FI CONNECTIONS i see that the ip-encap tunnel to the cisco router have Public2 connection mark, but it should go trohgh Public. when i stop the rules in IP FIREWALL MANGLE that marks the connections and packets to the different ISP the tunnel works fine and i have ping, traceroute etc… After enabeling the rules everything stops!
How can i make the router to use only Public Interface to make the GRE tunnel?
edit: in Interface IPIP a have set my ip of the first ISP 83.228.X.X
You can’t make plain gre tunnels with RouterOS. 
You can make a PPTP tunnel or IPsec though.
colleagues from the office opposite only want it, L2TP or PPTP are not currently an option
Can someone help
like IPIP tunnel?
IPIP - yes
/interface ipip add
thast what i’m trying to do. but no result. the connection to the cisco is market as Public2 connection / in firewall Connection - Conn Mark / but it should bi only public conn.
how can i make some ip-addresses to go trought only one ISP, and not getting hit by PCC
# NAME MTU LOCAL-ADDRESS REMOTE-ADDRESS
0 R IP-IP 1400 83.228.X.X 84.242.X.X
the connection goes trought the 10.81.12.101
Sorry for my bad english.!
so mark it as public in output chain before it gets marked as Public2
Connection is not marked at the beginning?
0 ;;; Mark Incoming (to router itself) connections so their reply packets get routed to the interface the connections c>
in
chain=input action=mark-connection new-connection-mark=Public_conn passthrough=yes connection-state=new
in-interface=ADSL
1 chain=input action=mark-connection new-connection-mark=Public2_conn passthrough=yes connection-state=new
