Hello.

I connect to the internet using a satellite modem and i know of the latency caused by such systems
I've heard of whats called TCP Accelerators. I know what they do is ACK spoofing ...

Can this be done somehow with RouterOS?

It'd really be a wonderful thing so I dont have to consider buying a TCP Accelerator.

also, what should i set the MTU value for the Net adapter connected to the modem? (its connected directly using a crossover cable)

Please advise.

TCP ack spoofing and acceleration are very specialized functions that intercept the tcp socket and fake the endpoints at each end of the satellite connection. RouterOS cannot do this, it requires specially written code and tcp stack running on devices at each end of the satellite link symmetrically. iDirect and maybe some other satellite modems have this function built-in.

regarding the MTU, it depends on the satellite modem and router at each end, most likely the best setting is 1500.

The thing thats frustrating is browsing is a bit sluggish ... it takes about 10 or so seconds before a page starts to appear however when it does it comes in fast.

same with downloading. it starts off slow then slowly starts to catch up.

there must be a way to at least make browsing faster.

pls advise.

are you using a DNS cache?

are you using a DNS cache?

i assume you mean the RouterOS dns cache

Thats it.

I am considering a UDGateway device but i really really dont want to spend any money on any of this stuff if RouterOS has some sort of method we can work around this web browsing delay

Hi cylent, please check that: http://forum.mikrotik.com/viewtopic.php?f=2&t=21392 , I directly cannot navigate connecting a computer to the modem satelital, the only way is with the application. Try with debian + squid and mikrotik, but I am not able to decipher the form of emulating the aplicaicon.

i am confused as to the link you gave me
i did see the screenshot but who supplies this "Internet page accelerator" application?

I cant try with debian right now cause i dont have another box to use for that purpose.

Thank you for your interest, the application is provides by the provedor of the service satelital.

almost certainly the application is a custom windows XP software with unknown and proprietary functionality that must work together with the device at the satellite teleport where the service originates.

mikrotik OS has no way to intercept and modify or spoof tcp sockets as far as I know.

It is one it hurts, because sharing the application in xp can make it walk, but I would have to dedicate an alone pc for that reason and another to be proxy transparent. Sorry for the insistence but there has to exist a way of doing it more simple.
