ok so iam new to routerOS and i must say this makes a fancy billion router look like a new born's toy at a fraction of the cost :D
iam using a Routerboard RB750UP (6.15 OS) with a USB 3g card (huawei), i got everything working (bridge all the Ethernet ports , and got the 3g connection up)
now i need to setup an IPSEC VPN Tunnel between the routerboard and our Fortigate 100d firewall.
as soon as i go to IP->IPSEC->Policies->add and then loose connection (cant ping , telnet or winbox) right after i click ok in the New IPsec Policy window.
any ideas ? am i missing something ?
