Performance Problems with our RED15

MichaelKuban

Hello all,

I am Mike and glad to be here to get some help from professionals.

We have 2 SG210 in HA cluster here at our HQ in Germany and one RED15 in our small office in Italy. I configured the RED and now we have the problem that we have no speed between the two sites. I configured the RED as Standard / Unified and the speed was less than 1M. Now I switched to Standard/Split so that the users in Italy have a fast internet connection at least (20M). But the speed between the sites is still that bad.

Internal Network:

172.16.20.0/24

255.255.255.0

Red Network:

172.16.23.0/24

255.255.255.0

Masquerading Rule:

RED15 -> External (WAN)

Maybe you can help to figure the problem out. I will give you all the settings you will asking for :)

Thanks and regards

Mike

    Hi Mike,

    how exactly did you measure the speed? Did you do a download from the Internet or an internal transmission?

    Also, do you have some Linux boxes behind the RED and UTM? In this case maybe you could try a test with iperf to see which values you get there. It might also be worth a shot to reduce MTU sizes for server and client to something like 1100 (just as a test).


    Kind regards
