An emule user here as well. Having the same problem of connecting to "CERTAIN" emule server when connected to BolehRoute, namely eDonkeyServer No1 [92.241.164.30:4242] & eDonkeyServer No2 [212.63.206.35:4242], which supposingly to be the better servers. Had been facing this problem for quite some time but unable to find a solution for it.
However, you might want to try connecting to TVU DonkeyServer No1 [89.248.174.84:6543], when connected to BolehRoute & this should connect you fine.
