Nimbostratusoutbound iRule help
hey guys, i make a irule to use choose diffrent links as following:
when CLIENT_ACCEPTED {
if { [matchclass [IP::local_addr] equals $::CNC_class]} {
pool ISP-WANGTONG-FIRST
}
elseif { [matchclass [IP::local_addr] equals $::CT_class]} {
pool ISP-DIANXIN-FIRST
}
else {
pool ISP-GW-POOL
}
}
when LB_SELECTED {
if {[IP::addr [LB::server addr] equals 221.218.250.62] and [IP::addr [IP::client_addr] equals 10.6.1.1] or [IP::addr [IP::client_addr] equals 10.6.1.2] } {
snat 221.218.250.61
}
elseif {[IP::addr [LB::server addr] equals 202.224.233.89] and [IP::addr [IP::client_addr] equals 10.6.1.1] or [IP::addr [IP::client_addr] equals 10.6.1.2]} {
snat 202.224.233.90
}
else {
snat automap
}
}
Thank you for correcting me !

thank you for your reply!
well, the host 10.6.1.1 and 10.6.1.2 just be permited to use 221.218.250.61 as the source address to connect the remoter server, the other words, the two hosts just can go out with the one link. howerver we don't know the remoter server's IP address.
how could I to wirte the iRules, thank you very much!- monica_74227hey guys, I fixed the iRule, but always generate errors, thank you for your help:
when CLIENT_ACCEPTED {
if { [mathclass [IP::client_addr] equals $::Uni_client_class]} {
pool Uni_first_pool
}
elseif { [matchclass [IP::local_addr] equals $::Uni_class]} {
pool Uni_first_pool
}
elseif { [matchclass [IP::local_addr] equals $::CT_class]} {
pool CT_first_pool
}
else {
pool Default_gateway_pool
}
}
when LB_SELECTED {
if {[IP::addr [LB::server addr] equals 221.218.250.62] and [IP::addr [IP::client_addr] equals 12.10.10.2] or [IP::addr [IP::client_addr] equals 12.10.10.1] } {
snat 221.218.250.61
}
elseif {[IP::addr [LB::server addr] equals 202.224.233.89] and [IP::addr [IP::client_addr] equals 12.10.10.1] or [IP::addr [IP::client_addr] equals 12.10.10.2]} {
snat 202.224.233.90
}
else {
snat automap
}
}
thank you very much!

There is a typo: mathclass should be matchclass. Also, you should use parentheses to ensure the logic in LB_SELECTED is correct:
if { ([IP::addr [LB::server addr] equals 221.218.250.62] and [IP::addr [IP::client_addr] equals 12.10.10.2]) or ([IP::addr [IP::client_addr] equals 12.10.10.1]) } {
...
elseif { ([IP::addr [LB::server addr] equals 202.224.233.89] and [IP::addr [IP::client_addr] equals 12.10.10.1]) or ([IP::addr [IP::client_addr] equals 12.10.10.2])} {
