MikroTik

i have a verry strange problem...
i configured a lot of eoip tunnels with bridging but this problem really bugs me.. so all you network wizz, pls give me a hand...

local lan---------router A -----eoip-------router B-------local lan

both routers do bridging... of the eoip interface and the local lan interface.
both eoip endpoint have a non-existing mac adress on them.
the eoip and the local lan and the underlying interfaces all have arp enabled.
router a has local lan set to proxy-arp, for the PPTP dailin users with the same ip's as the local lan interface

so i see traffic flowing in the bridge on both i see traffic on the eoip interface on both... now the problem...

if ip ping from router A to a router B adress on the local lan i get no reply.
if i ping from a pc after router A to a router B adress no reply...
not even arp...
if i ping from router B to router A or a pc after router A instant reply...
i get arp entries in both routers and pc
if i then ping from router A to B it works
ping from pc to router B works

after about 5 min of no traffic from router B...my reply from the router and pc time-out.
if i look in the router A arp table the adress is still there.
in the pc it says mac 00:00:00:00:00:00 invallid
if i ping from router B to A or the pc i have no reply...
if i now delete the arp from router A and from the PC
i have ping reply again in both directions for 5 minutes...

so my conclusion is.... arp reply and request comming from router B to A or pc work...
arp reply/requests from router A or pc to router B don't

i have absolutly no idea what to do...
