iptables forwarding through pptp

Question

I am creating my own AOSP that contains my own apps and services. One of those services creates ppp0 interface and tries to link specific apps to be forwarded through that interface. I have tried these commands but it was not working as expected.

iptables -t mangle -A OUTPUT -m owner --uid-owner 10088 -j MARK --set-mark 100

ip route add via 10.0.0.201 dev ppp0 table 100

ip rule add from all fwmark 100 table 100

iptables -t nat -A POSTROUTING -m owner --uid-owner 10088 -j SNAT --to-source 10.0.0.201

ip route add default dev wlan0

By the way, 10.0.0.201 is ppp0 interface Ip address.

This works fine with the user 10088, however when I use android chrome browser(which is NOT WITH UID 10088), I have a DNS problem, so any URL can not be resolved this means no internet except for my user with UID 10088.

I have analysed androids iptables after enabling vpn and I have found these lines:

-A st_mangle_OUTPUT -m mark --mark 0x3c -g st_mangle_ppp0_OUTPUT
-A st_mangle_OUTPUT -m owner --uid-owner 0-99999 -g st_mangle_ppp0_OUTPUT
-A st_mangle_ppp0_OUTPUT -j MARK --set-xmark 0x0/0xffffffff
-A st_mangle_ppp0_OUTPUT -j MARK --set-xmark 0x3c/0xffffffff

It sounds that they mark some packets and chose a range of uids, exactly what I want to do EXCEPT I wanna have specific uids not a range of them.

ip route provides me this:

218.75.4.130 via 192.168.0.1 dev wlan0 
218.189.210.4 via 192.168.0.1 dev wlan0 

I am looking for any solution that makes my job done, either solving this or another new solution.

looking forward to hear from you.

Thanks at advance.
