Beginner issues with RB750

arpadffy · Mon Jan 17, 2011 2:51 am

Hello,

I have recently purchased an RB750 in order to solve some 3WAN 1 LAN routing issues on a small but sensitive network environment.

I run 5.0rc7 and it shows that the RB has licence level 4 upgradeable to 6.x.

As a beginner to ROS, I have followed the excellent wiki documentation word by word, regardless I faced some major issues.

It was a piece of cake to set up the first WAN interface (that use DHCP)
The second WAN interface has a static IP (no problem at all), but the 3rd that use PPPoE does not work at all. The log shows a never ending initializing, dialing, terminating disconnected cycle.
Passwords are OK.Using the right interface...modem is connected and works with an another router.
...even the PPPoE Scan can not find any available server.

Also another issue is that can not get IPv6 6to4 tunnel working.
I have configured according to the HE's recommendation. The tunnel is fully functional from Linux router.

/interface 6to4 add comment="Hurricane Electric IPv6 Tunnel Broker" disabled=no local-address=83.251.66.185 mtu=1280 name=sit1 remote-address=64.71.128.82
/ipv6 route add comment="" disabled=no distance=1 dst-address=2000::/3 gateway=2001:470:1F00:FFFF::6B0 scope=30 target-scope=10
/ipv6 address add address=2001:470:1F00:FFFF::6b1/64 advertise=yes disabled=no eui-64=no interface=sit1

I wonder, am I doing something very wrong or I have a licence related problem and those operations are not allowed with my licence or RB750 is not designed for this.

Any help would be appreciated.

Thank you in advance.

Regards,
Z

Update.

by creating a new tunnel on HE's site... the ipv6 related issue is solved.
Do not ask me why, but it works perfect now... (indeed, it would be nice to have radvd functionality in the router)

Thank you.

...by the end of the day I was able to make PPPoE working.
I do not why, but it did not work on ether5, but the very same configuration on ether3 worked perfect.

I considered until now all five ports equal - but from now I will try not to use ether5 for other task but local switching.

Is this a right approach? Could anybody point me to some documentation about this issue?

Thank you.

Thank you.

With RouterOS v5rc8 all my radvd related problems (and all others) are solved.

Hello,

With RouterOS v5rc8 all my radvd related problems (and all others) are solved.

Unfortunately, I need to reopen this thread as with ROS v5.0 I again have problem with IPv6 (same configuration).

The IPv6 works perfectly from the router out to the Internet. can ping trace route works etc.

Within the LAN it works OK

[admin@MikroTik] > ipv6 route print detail
Flags: X - disabled, A - active, D - dynamic, C - connect, S - static, r - rip, o - ospf, b - bgp, U - unreachable
 0 A S  dst-address=::/0 gateway=sit1 gateway-status=sit1 reachable distance=1 scope=30 target-scope=10

 1 A S  dst-address=2000::/3 gateway=sit1 gateway-status=sit1 reachable check-gateway=ping distance=1 scope=30 target-scope=10

 2 ADC  dst-address=2001:470:27:5b6::/64 gateway=sit1 gateway-status=sit1 reachable distance=0 scope=10

[admin@MikroTik] > ipv6 firewall filter print
Flags: X - disabled, I - invalid, D - dynamic
 0   chain=input action=accept protocol=icmpv6

 1   chain=input action=accept

 2   chain=forward action=accept

Ping out works in does not

[admin@MikroTik] > ipv6 firewall mangle print

[admin@MikroTik] > ping 2001:470:27:5b6::1
