#1
If you are really creating another routing instance for ISP2, then LAN interface also should be within that instance.
Unless you're using policy based filtering.
#2
Explain pool "cifra1" (79.134.86.54/32), is it routed to your isp2 wan interface or resides within the same subnet.
If it is within the same subnet, you should configure proxy arp for that.
It could help if you paste the full config once it is configured to run over ISP2 (hide all the sensitive info)
