Hi,
I have 2 PPPOE WAN connection with same ISP and When the connections are established the gateways become identical due to CGNAT.
As a result PF route-to round robin load balancing rule does not works because of the identical gateways.Thanks in advance

Code: 
pppoe_igb0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 mtu 1492
    inet E.F.G.H --> A.B.C.D netmask 0xffffffff
    inet6 fe80::e63a:6eff:fe49:cc4e%pppoe_igb0 prefixlen 64 scopeid 0xa
    nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
pppoe_igb1: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 mtu 1492
    inet J.K.L.M.N --> A.B.C.D netmask 0xffffffff
    inet6 fe80::e63a:6eff:fe49:cc4e%pppoe_igb1 prefixlen 64 scopeid 0xb
    nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>

ask isp if they support multi link ppp
also iirc you can change his_addr with ifconfig and still works

Hi , there is no chance with isp they has not mlpp support
I am confused with iirc and his_addr . How can i change the gw IP address without VDSL Router NAT or care there any PF route-to option to overcome this problem?
 
Code: 
#ifconfig ng0
ng0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> metric 0 mtu 1492
    inet 86.xx.xx.x8 --> 10.0.0.1 netmask 0xffffffff

like this
put something in the iface-up script for ppp(8) or mpd5 whichever you use
