Transparent Traffic Shaper

i have a mikrotik acting as a traffic shaper on a network. the main router is a cisco which is managing vpn. is there a way to get the trasparent shaper to also act as a transparent proxy?

cisco - 192.168.2.64
mikrotik transparent shaper - 192.168.2.254
lan - 192.168.2.0/24

Enable proxy on MikroTik router, add NAT redirect rule to catch HTTP traffic and forward it to the router itself.

i have done the following

[admin@MikroTik] /ip proxy> print
enabled: yes
src-address: 0.0.0.0
port: 8080
parent-proxy: 0.0.0.0
parent-proxy-port: 0
cache-administrator: bsat
max-cache-size: none
cache-on-disk: no
max-client-connections: 600
max-server-connections: 600
max-fresh-time: 3d
serialize-connections: no
always-from-cache: no
cache-hit-dscp: 4
cache-drive: system

[admin@MikroTik] /ip firewall nat> print
Flags: X - disabled, I - invalid, D - dynamic
0 chain=dstnat action=redirect to-ports=8080 protocol=tcp dst-port=80

Unfortunately these just kills all browsing. The router is in bridge mode and has no routes or nat rules. can the router do both transparent shaping and routing??

Enable bridge settings /interface bridge settings set use-ip-firewall=yes.

thanks for the reply

i had this setting enabled before as this is a standard setting in the transparent traffic shaper setting as per http://wiki.mikrotik.com/wiki/TransparentTrafficShaper. the only thing i did not do was the mangle as that is for type of traffic shaping whereas i am using it only for per ip shaping.

any ideas?
thanks in advance
