Hi ivdouden,  
Yes, it should work like that way by default.  
Here is the example:  
I have 2 VIPs (.14 and .15) on the eth2/ ve56 (MAC: 000c.2953.20b9).

```yaml
vThunderADC#sh run | incl slb vir
slb virtual-server Web14 10.0.56.14
slb virtual-server Web15 10.0.56.15

```

```yaml
vThunderADC#sh int br
Port  Link Dupl Speed Trunk Vlan MAC       IP Address     IPs Name
------------------------------------------------------------------------------------
mgmt  Up  Full 1000  N/A  N/A 000c.2953.20af 172.20.15.101/16   1
1    Up  Full 10000 none 56  000c.2953.20b9 0.0.0.0/0       0
2    Up  Full 10000 none 1  000c.2953.20c3 10.0.255.101/24    1
ve56  Up  N/A  N/A  N/A  56  000c.2953.20b9 10.0.56.101/24    1

```

On my upstream router, i see both VIP with the same MAC address:

```yaml
 GW>sh arp
Address     Age (min) Hardware Addr  Interface
10.0.56.14      N/A 000c.2953.20b9 Vlan10, Ethernet46
10.0.56.15      N/A 000c.2953.20b9 Vlan10, Ethernet46
10.0.56.101     N/A 000c.2953.20b9 Vlan10, Ethernet46

```

Hope it helps.
