Hi, Enabling the NTP Server on CHR requires installing the adittional [ntp] package. After installing this package, the NTP Client is missing some of the features available in the basic package. NTP servers cannot be choosed by name, only by IP address. On the Winbox GUI all the diagnostic informati...

Hi,

I tried to assemble this equipment using a standard indoor case and it doesn't fit:



Do you know it there will be a new version of the indoor cases or the routerboard?

Am I doing something wrong?

I have a 433UAH in I get exactly the same problem: after the upgrade, eth2 and eth3 are dead.

It works fine with 4.2.

ok, just installed 4.3 on a 433uah and it basically turned two of the interface into "ghost interfaces" (everything looks normal, no traffic going over them)
downgraded back to 4.2 and all good again

Just an FYI

Same model, same problem and same solution.

I have built the following arrangement: RB750 (V4.2 PPTP Server + L2TP Server) connected to several RB4XX (V4.2 PPTP Client + L2TP Client). Every client creates a PPTP and a L2TP tunnel to the server, through the same link and with equivalent settings. L2TP tunnels stay connected forewer. PPTP tunne...

Switched the PPTP tunnel to L2TP.

Downgraded Server Router to V3.3
Upgraded it again to V4.2
All clients came alive for some minutes.
Created L2TP tunnels and changed routing table accordingly.

I downgraded RB750 to V3.30 and one of the "died" clients is connecting again.

Settings remain the same, and clients are still running V4.2.

The other still don't connect.

Looks like a timing problem in the PPTP protocol.

By the way:

I dowgraded to V3.30 and apparently the RB750 is happy with the V4 key...

Hi, I would like to downgrade a RB750 to V3.30. Unfortunately, during the V3 to V4 upgrade a xxxx-yyy.key file was not generated. I have checked other RB4XX systems, and they all have the xxx-yyy.key for V3 in the "files". Is there any way to downgrade the RB750 to V3.30 and get the V3 key...

Which OS version are you using?

What makes you think it is a firewall problem?

Hi, I have a RB750 V4.2 working as a PPTP Server. Several clients using RB433 V4.2 and RB493 V4.2 routerboards connect to this server. In the past (since the release of V4.2) clients could connect without problems. The first client stopped working a few days ago. The second client died today. Anothe...
