Re: bonding wireless for maximum throughput

I'm afraid I'm not able to repeat your results. Both WLAN1 and WLAN2 on either side have wireless registration of 45dBm or better and connect at 54Mbps for both rx and tx. In fact I have even fixed the rates on either side. CPU is not an issue < 20%. With both iterfaces enabled the best I can get by...

Re: bonding wireless for maximum throughput

I have applied the exact config as described by KimC above with two RB600 with R52H cards running ROS3.6. However if I copy a file between two devices on either side of the link the bonding performance with two interfaces is worse than when I use just one of the links in the bonding interface. While...

Everything works very well, except that I cannot connect to the PPTP server from my VPN client once I have made a sucessfull connection from my Win XP VPN client. Traffic to other hosts on the subnet is fine. Is there perhaps a setting that one can set to be a...

The link is very intermittent and I get high packet loss although the devices have good signals levels (better than -68dbm 99% of the time) according to the registation tables. The problem seems to be worse at certain times. Below find some detail: Ping between ...

Best max-mtu value for ADSL?

Mikrotik recommends a max-mtu of 1480 as the optimal value. However most ISP's recomend 1492 for ADSL (1500-8 bytes overhead for PPPoE). If my ISP recommends 1492, should I still set the value of 1480 on my Mikrotik as per the Mikrotik documentation?

SMTP fixup causes the problem

Ok I found something. The problem is related to the SMTP fixup setting on the PIX. If I disable the fixup for smtp on the PIX my problem is solved.

I however don't understanbd why the PIX smtp fixup stops the MT email client?

Yes it is possible. We're already running muliple hotspots with VLAN's on 2.9. Create VLAN interfaces as sub interfaces of your hotspot interface and then specify the VLAN interface as the relevant hotspot interface

It would be great if the DNS name of the SMTP server that is used for relaying email in the hotspot can be specified rather than a IP address.
