DST-NAT redirect action: To-dst-address dont work

HI

I am trying to make a proxy-web server in a DMZ arquitectury, but not work the DST-NAT, redirect action, to-dst-addres option (mikrotik 2.8):

ip firewall dst-nat src-addres=networksubnet protocol=tcp dst-port=80 action=redirect to-dst-address=proxyip to-dst-port=defaultproxyport

networksubnet: 192.168.1.0/24
proxyip: 192.168.2.2

anterior post in this forum says (for example):

http://forum.mikrotik.com//viewtopic.php?t=628&highlight=squid

some solutions are:

enable parent-proxy

http://forum.mikrotik.com//viewtopic.php?t=304&highlight=squid

but this dont work to me for hardware limitations: (not suficient memory in mikrotik router to enable de proxy: is the error when a try to enable the proxy)…

I want to know if in the 2.9 mikrotik version the dst-nat redirect action to-dst-address option is working. (or the similar commands in mktk 2,9)

thanks in advance

What hardware do you use for Mikrotik?

yes, redirection works fine.
to redirect some traffic use following rule:
chain=dstnat protocol=tcp in-interface=ether1 dst-port=80 action=redirect
to-ports=8080

Ok in miktk 2.8 this option work fine (redirects the port 80 to the 8080 mikrotiks port), but when to this action I set to-dst-address option, the rules dont work (no redirecct to the target address),I want to know if in mktk 2.9 I put the dst-adrres option work the redirect to the web-proxy-dmz machine?

Mi Hardware:

Pentium I 250 Mhz, 60 Mb RAM, 4 NICs pci Dlink.

thanks in advance
