dhcp, multi inerface

This is in my Home and for home use...

My setup
UTM9 10.10.50.1
eth0 - Cisco 1140 Access point. 2 vlans. Home WiFi (vlan2 10.10.50.100), Guest WiFi (vlan3 10.10.20.1) (I cant get native vlan1 to work so I used 2 & 3)
eth1 - Cable modem
eth2 - DSL modem
eth3 - Internal LAN

What I am trying to do is to setup DHCP on eth3 as 10.10.50.151-200 and DHCP on eth0(vlan2) as 10.10.50.101-149

I connect to each interface and I do get an appropriate IP from each DHCP.
I get internet access on eth0(vlan3) and eth3

I do not get internet access on Home wifi eth0(vlan2)

I think it has something to do with the gateway address but I cant figure it out.

I tried 10.10.50.1 and 10.10.50.100 with no luck.
Any pointers?
Thanks.

It's easy when you understand that, in IPv4, there are 32 address bits = four octets(bytes). The CIDR "/" notation is just the number of leading "1" bits in the netmask. 255.255.255.128 = 11111111 11111111 11111111 10000000 = /25

I usually check my work at Online IP CIDR / VLSM Supernet Calculator
