Proxy TRansparent Mode

[bentunx]

hi guys

i have some problem while implementing Proxy in transparent mode
everything is working fine in standard mode with port 3128, but if i switch into transparent mode client cant browsing

btw here is the topology :
WAN
|
|
|
(static IP) WAN
PfSense
(10.9.8.1/24) LAN
|
|
|
(10.9.8.7/24)
Router –-------------------|
(172.16.99.1)         (172.16.1.0)
|                                |
|                                |
(172.16.99.0/24) (172.16.1.0/24)
(Client Lan1) (Client Lan2)

Here is my PFsense NAT dan Rules
NAT
WAN 10.9.8.0/24 * * * WAN address *
WAN 172.16.99.0/24 * * * WAN address *

RULES
IPv4 * LAN net * * * * none  
IPv4 * 172.16.99.0/24 * LAN address * * none   Default allow LAN to any rule
IPv6 * LAN net * * * * none   Default allow LAN IPv6 to any rule

Yeah, obvious hint here would be getting rid of the redundant router behind pfSense that's producing double NAT, requires static routes configured on pfSense and generally is a royal PITA.
