ALRIGHT, I figured out the solution in a timely manner. From: This dude. Basically one needs to use iproute2 in order to allow traffic shaping. It could probably be done with iptables, but I know nothing and you can have fun with that. <Generalization starts now> iproute2 contains tables which can be checked using iprules You will want separate tables for each device probably. Start by editing the /etc/iproute2/rt_tables #nano /etc/iproute2/rt_tables Now add two new tables to the bottom of the file, it looks roughly like this: # # reserved values # 255 local 254 main 253 default 0 unspec # # local # # #1 inr.ruhep now add: # # reserved values # 255 local 254 main 253 default 0 unspec # # local # # #1 inr.ruhep 1 WAN1 2 LAN1 Now save and we have some tables. Next start is to actually ADD something to the tables. I will use an example yyy.yyy.yyy.yyy for wan and xxx.xxx.xxx.xxx for lan. For this part yyy.yyy.yyy.yyy and xxx.xxx.xxx.xxx should be the GATEWAY the interface is connected to. I do not know whether to create a new table for eth0:0 or vlan type setups. Will append later. from the terminal: #ip route add default via yyy.yyy.yyy.yyy dev eth0 tab 1 #ip route add default via xxx.xxx.xxx.xxx dev eth1 tab 2 Now check the tables. #ip route show table 1 default via via yyy.yyy.yyy.yyy dev eth0 #ip route show table 2 default via xxx.xxx.xxx.xxx dev eth1 Everything should be shiny and now we need RULES. yyy.yyy.yyy.yyy/ww and xxx.xxx.xxx.xxx/zz should be IP ADDRESSES while ww and zz are the subnet in CIDR notation and are assigned to the interfaces eth0 and eth1. e.g. 192.168.0.100/24 tl;dr yyy.yyy.yyy.yyy/ww = 192.168.0.100/24 CIDR Notation yyy.yyy.yyy.yyy is the IP ADDRESS of the interface. type in the terminal: #ip rule add from yyy.yyy.yyy.yyy/ww tab 1 priority 500 #ip rule add from xxx.xxx.xxx.xxx/zz tab 2 priority 600 Another e.g. just to get the point across: #ip rule add from 192.168.0.100/24 tab 1 priority 500 Now we check to make sure the rules are added: #ip rule show 0: from all lookup local 500: from yyy.yyy.yyy.yyy lookup wan1 600: from xxx.xxx.xxx.xxx lookup lan1 32766: from all lookup main 32767: from all lookup 253 We are almost done: #ip route flush cache Now we should be done. I have run into a problem. (nvm)The changes do not stay and I will figure out a way to keep the changes saved(/nvm). edit: Alright to make the changes permanent we must edit /etc/rc.d/rc.local #nano /etc/rc.d/rc.local Append ip route add default via yyy.yyy.yyy.yyy dev eth0 tab 1 #GATEWAY 1 ip route add default via xxx.xxx.xxx.xxx dev eth1 tab 2 #GATEWAY 2 ip rule add from yyy.yyy.yyy.yyy/ww tab 1 priority 500 #IP ADDRESS 1 ip rule add from xxx.xxx.xxx.xxx/zz tab 2 priority 600 #IP ADDRESS 2 To the BOTTOM of the file. We are done. In conclusion: This is why we cannot have nice things. tl;dr I know nothing. -Romoku
