BIG-IP Version 9.3 routing - address translation problem

I am tring to setup traffic between two internal vlans (10.1.0.0 and 10.2.1.0). It works but the bigip is translating the source address to itself.

Client (10.2.1.64): mysql -h 10.1.2.14 -u whatever -p

Server (10.1.2.14):
root@i-db0:~  netstat -an4 | grep 3306 | grep 10.1.2.14
tcp4       0      0 10.1.2.14.3306         10.1.1.240.37105       ESTABLISHED

Bigip1 - self addresses 10.1.1.240 (floating) 10.1.1.241 and 10.2.1.240 (floating) and 10.2.1.241
Client - host address: 10.2.1.64/24, gateway set to 10.2.1.240
Server - host address: 10.1.2.200/16, gateway set to 10.1.1.240

traceroute to 10.1.2.14 (10.1.2.14), 64 hops max, 52 byte packets
 1  bigip01-snat (10.2.1.241)  0.316 ms  0.189 ms  0.178 ms
 2  i-db0 (10.1.2.14)  0.464 ms  0.443 ms  0.346 ms

and back

traceroute to 10.2.1.64 (10.2.1.64), 64 hops max, 52 byte packets
 1  bigip1 (10.1.1.241)  0.228 ms  0.175 ms  0.153 ms
 2  i-proxy1 (10.2.1.64)  0.454 ms  0.376 ms  0.305 ms

Here is the bigip configuration:

BIG-IP Version 9.3.1 81.1

self 10.1.1.240 {
   netmask 255.255.0.0
   unit 1
   floating enable
   vlan Default
   allow default
}
self 10.2.1.240 {
   netmask 255.255.255.0
   unit 1
   floating enable
   vlan Default
   allow default
}

I tried adding this and it didn't change anything.

virtual vs-forward {
   destination 10.2.1.0:any
   ip forward
   ip protocol tcp
   mask 255.255.255.0
   translate address disable
   translate service disable
   profile forward-fastl4
}

Any help would be appreciated.
