I’m facing strange problems with recently adquired RB201 equipment. After trying to reset the configuration with the objective of making a new whole config from scratch without any result, I’ve made a configuration reset to the factory settings and, changing only the eth1 IP config, I’ve discovered that assigning static IP address to an interface didn’t works with this router.
I’ve tried all the above with the installed version of RouterOS (6.29.1) first and, after the factory reset, I’ve upgraded to the last version (6.34.2) with the same result.
First of all I suspected about firewall, but finally I’ve discarded it and found that the factory configuration has a DHCP client on the eth1 interface that works well, but removing this one and setting static IP results in lost of IP connectivity to this interface.
The resulting scenario is the impossibility to use this router with a static IP from the ISP, also not to use it in any scenario that requires a configuration made from scratch.
Does anybody had this problem before? Does exist a solution to this strange, and sad, issue?
First thing to check is System > Routerboard Firmware.
Assuming is up to date, did you try a reset to no defaults (/system reset-configuration no-defaults=yes)? that should wipe all the router configuration.
Thank you for your reply. Prior to my post I’ve tried to reset the configuration leaving it “blank” and the behaviour is the same, static IP configuration doesn’t work.
The thing I can’t understand is why works getting dynamic IP from DHCP and not with static IP configuration. Does this router have any hardcoded limitation?
Things are going worst… now it is impossible to ping the router on the eth1 with dynamic IP too and the router can’t reach the default gateway got by DHCP.
Getting out the eth2-master from the bridge and configuring static IP it can ping other hosts, but those same hosts can’t ping the eth2-master interface. Static default route doesn’t work because the gateway (next-hop) is considered unreachable… but the router can ping it!
I’ve never seen this behaviour in any CCR, CRS nor RB that I’ve worked with before… and I’ve managed to achieve more complex configurations with little boxes, for example RB750, not only including static routing but also BGP and VPLS.
I’m thinking the solution is to downgrade to a previous version, I know about RB2011 working with 6.27. I’ll try with this version and post the result here.
