I have two networks connected via ipsec with openswan. Each network contains one samba server managing one workgroup each one. The network structure is the following one: Network 131.0.0.0/16--Samba: 131.0.0.106 (workgroup groupa) --- 200.x.x.x ----internet----- 64.x.x.x ---- Samba: 192.168.1.1 (workgroup groupb)--Network 192.168.1.0/24 Machines in groupa (network 131.0.0.0/16): pc3 (131.0.0.2, windows), avda1 (131.0.0.106, linux samba) Machines in groupb (network 192.168.1.0/24): pc01 (192.168.1.2, windows), rqta1 (192.168.1.1, linux samba) Server 131.0.0.106 is a WINS server for both networks. Each client in both network points wins server to 131.0.0.106. The problem is that I can't browse the workgroup in the other network. If I put \\pc01 or \\rqta1 on network neighborhood (pc01 and rqta1=groupb) from pc3 (groupa) I can see the shares (it's ok). Also I can see \\pc3 and \\avda1 from pc01. This means WINS works fine. But I can't browse the list of machines of the other network. For example: in pc01 I can't see the list of machines of groupa. In pc3 I can't see the list of machines of groupb. #----smb.conf (131.0.0.106) workgroup = groupa wins support = yes domain master = yes local master = yes preferred master = yes remote browse sync = 192.168.1.1 remote announce = 192.168.1.1 name resolve order = wins bcast security = share #----smb.conf (192.168.1.1) workgroup = groupb wins server = 131.0.0.106 wins proxy = yes domain master = yes local master = yes preferred master = yes remote browse sync = 131.0.0.106 remote announce = 131.0.0.106 name resolve order = wins bcast security = share I also tried without remote browse sync and remote announce, also security=user, also without domain master in groupb. I guess WINS works fine, because it can resolve any name in both networks, but why I can't browse?
