Default [Solved] Cannot access from internet on 2nd ISP

Hi,
I have a OpenBSD 4.9 with 3 NICs. For testing purposes pf is disabled. I can connect to services (eg. ssh) from internet via 1st ISP (shh 78.w.x.y, ping works) but i cant connect via 2nd ISP (ssh 178.w.x.y, ping dosent work). I would like to reach my server from two ISP at the same time. Here is my config:

1st NIC (gateway for lan):
Code:
fxp0: flags=8b43<UP,BROADCAST,RUNNING,PROMISC,ALLMULTI,SIMPLEX,MULTICAST> mtu 1500
        lladdr 00:1b:21:22:f3:82
        priority: 0
        media: Ethernet autoselect (100baseTX full-duplex)
        status: active
        inet6 fe80::21b:21ff:fe22:f382%fxp0 prefixlen 64 scopeid 0x3
        inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255
2nd NIC - pppoe0 via bge0 (1st ISP)
Gateway: 87.w.x.y
Code:
pppoe0: flags=8951<UP,POINTOPOINT,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1492
        priority: 0
        dev: bge0 state: session
        sid: 0x1504 PADI retries: 1 PADR retries: 0 time: 21:47:47
        sppp: phase network authproto pap authname "xxxxxxxxxxxx@y.pl"
        groups: pppoe egress
        status: active
        inet6 fe80::21b:21ff:feb5:5899%pppoe0 ->  prefixlen 64 scopeid 0x6
        inet 78.w.x.y --> 87.w.x.y netmask 0xffffffff
3rd (2nd ISP)
Gateway: 178.w.x.254
Code:
em0: flags=8b43<UP,BROADCAST,RUNNING,PROMISC,ALLMULTI,SIMPLEX,MULTICAST> mtu 1500
        lladdr 00:1b:xx:xx:xx:xx
        description: 2/2
        priority: 0
        media: Ethernet autoselect (100baseTX full-duplex,rxpause,txpause)
        status: active
        inet6 fe80::21b:21ff:feb5:5899%em0 prefixlen 64 scopeid 0x1
        inet 178.w.x.y netmask 0xffffff00 broadcast 178.w.x.255
