Issue with IPSec between NATed Mikrotik and Cisco router

Hello, I am facing a problem with a RB760iGS I just bought. I have created an IPSec site-to-site VPN between this Mikrotik and a Cisco router. The Mikrotik is behind a NAT, set up as DMZ, so it has a private LAN interface (192.168.88.0/24) and a WAN interface with private IP (192.168.1.5). Its gatew...

Re: BGP Full Table time

It's not very quick, but once peer is established you won't have any issues for months.

Re: Very high cpu usage with 20+ sstp clients

I tried also pptp but sstp is like skype: it works everytime, with static or dynamic ip and behind any kind of nat and firewall.

Re: Very high cpu usage with 20+ sstp clients

I am using 5.19

any change about sstp in 5.20? I'd rather not upgrade a production router without a good reason.

Very high cpu usage with 20+ sstp clients

Hello, I am running some mikrotik routers with sstp server. I have two different situations, both with about 20-30 sstp clients (mikrotik 751); I get in both routers 100% cpu usage; this is not really a problem because it is responsive and gives good speed in sstp tunnels. what do you need to debug ...

Re: NEW PRODUCT - Cloud Core Router

we are using RB1100AH to estabilish bgp connections with full routing tables but we are getting often 80% cpu usages and higher sometimes, how will this one behave? Maybe it will not die with 2 full sessions? that would be awesome.

Re: recovering lost cpe wrongly set as wireless client in br

fixed it. real mac ends in D5 and the radio was answering to arp requests saying it was on D4. I forced an arp entry with D5 and telnet worked :D
bridge killed istantly and mac-telnet then worked again.

Re: api stops working with "cannot get challenge" on 5.0rc7

that's a bit risky during the week for a main router, is there something I can do to have api working again before upgrading?

Also telnet answered "connection refused", so I disabled and enabled it and it worked; after some hours connec...
