based on this topic: http://forum.mikrotik.com/t/solved-ospf-multiple-gateways/80341/1
now everything regarding the ospf and VPN is working.. although i discovered a different problem:
i had to activate proxy-arp for l2tp/ipsec roadwarrior on eth2. With this activated it seems that sometimes packets that should go to the 254 gateway arrive at the 250 (but never the other way around!). I tried to use a different switch but it seems like the switch(es) are not the issue.
Therefore users are getting kicked out of sessions (coming with a different wan-ips every couple of minutes or sometimes seconds)
since my interface-based routing seems a bit sloppy anyway, i thought about marking the packages, but i don’t seem to find a way to mark packets that arive at a certain gateway.
Anyone got any ideas? turning off proxy-arp is sadly not an option since the road-warrior won’t work otherwise.
Thanks in advance!
