In answer to my previous post.. As being a person who don't gives up too
soon.. I've figured solution out yesterday.

After submitting

ebtables -t broute -F
ebtables -t broute -A BROUTING -p ipv4 -d gg:gg:gg:gg:gg:gg --ip-dst
A.B.C.0/24 --ip-src A.B.D.0/24 -j redirect --redirect-target ACCEPT

I've noticed that it actually works, because ping dropped by half, from
100 ms to 50 ms.. so the solution Was simple:

ebtables -t broute -F
ebtables -t broute -A BROUTING -p ipv4 -d gg:gg:gg:gg:gg:gg --ip-dst
A.B.C.0/24 --ip-src A.B.D.0/24 -j redirect --redirect-target ACCEPT
ebtables -t broute -A BROUTING -p ipv4 -d gg:gg:gg:gg:gg:gg --ip-dst
A.B.D.0/24 --ip-src A.B.C.0/24 -j redirect --redirect-target ACCEPT

that moment ping dropped to <1 ms..
